Calcium Sulfate (Product Code: SCI-714/315) is an analytical reagent grade calcium salt, the compound behind gypsum and plaster of Paris, used to study permanent water hardness, sparingly soluble salts and the setting of plaster in school and college laboratories. It comes as a 100 g pack with an MSDS, a practical quantity for demonstrations and group work. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to institutions buying school chemistry lab equipment in India.

Specifications

What Is Calcium Sulfate Used For?

Dissolving a little Calcium Sulfate in distilled water gives a model of permanently hard water: boiling does not soften it, but adding washing soda precipitates calcium carbonate and removes the hardness. Shaking samples with soap solution before and after treatment lets students compare the lather and see the difference for themselves.

The salt also links chemistry to everyday materials. Gypsum is the dihydrate, gentle heating turns it into the hemihydrate known as plaster of Paris, and that plaster sets hard again when mixed with water. Because Calcium Sulfate dissolves only slightly, it is also a clear example in solubility and precipitation lessons, and the anhydrous form is used as a drying agent.

What to Specify When Ordering

• The form you need: anhydrous, dihydrate (gypsum) or hemihydrate, since the listing does not state it.
• The number of 100 g packs required.
• Any companion reagents for hardness practicals, such as washing soda, to be quoted together.
• The delivery destination, within India or overseas.

Frequently Asked Questions

What is Calcium Sulfate used for in the laboratory?
Calcium Sulfate is used to model permanent water hardness, to show how gypsum and plaster of Paris are related, and as an example of a sparingly soluble salt in precipitation lessons. Its anhydrous form also serves as a drying agent in general laboratory work.

Is Calcium Sulfate the same as gypsum or plaster of Paris?
Calcium Sulfate is the chemical behind both: gypsum is the dihydrate, and plaster of Paris is the hemihydrate made by heating gypsum. This listing does not state which form the analytical reagent pack contains, so confirm the form you need when you enquire.

Why is Calcium Sulfate used to model permanent hardness?
Calcium Sulfate causes permanent hardness because boiling does not remove it, unlike calcium hydrogencarbonate. A dilute solution lets students test lather with soap, then soften the water with washing soda, which precipitates the calcium as calcium carbonate.

Does Calcium Sulfate dissolve in water?
Calcium Sulfate dissolves only slightly in water, so a stirred suspension leaves undissolved solid behind and gives a saturated solution. That low solubility makes it a useful contrast with very soluble calcium salts such as calcium chloride in solubility lessons.

What is the shelf life of Calcium Sulfate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Calcium Sulfate. Ask us for the expiry date of the batch you are quoted, and keep the pack sealed, because the anhydrous form picks up moisture from air.

How can an institution order Calcium Sulfate?
Institutions and dealers can order Calcium Sulfate by sending the number of 100 g packs, the form required and the delivery address. Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, then sends a quotation for supply within India or to international markets.

Potassium Sulfate (Product Code: SCI-717/316) is an analytical reagent grade potassium salt used to prepare potash alum crystals, show the lilac potassium flame and teach sulfate chemistry in school and college laboratories. Agriculture and environmental science students also know it as sulfate of potash, a chloride-free fertiliser; this listing is a 100 g pack with MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which supplies reagents alongside chemistry lab equipment in India.

Specifications

What Is Potassium Sulfate Used For?

The standard double-salt practical dissolves Potassium Sulfate and aluminium sulfate together in hot water and lets the solution cool slowly, so that clear octahedral crystals of potash alum separate. Students learn that a double salt has its own crystal shape yet still gives the tests of each of its ions.

In qualitative analysis, a clean wire loop dipped in the salt gives a lilac flame that is easier to see through blue cobalt glass, while barium chloride solution gives a white precipitate confirming sulfate. The salt is stable and not strongly hygroscopic, so it weighs out easily. Wear goggles and avoid breathing the dust, as the MSDS advises.

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab and supplies Potassium Sulfate from Ambala, Haryana, sourcing analytical reagents for institutional chemistry stores. Buyers can combine this salt with the aluminium sulfate and glassware needed for alum preparation on one order. Visit the ScienceLab profile to learn more about the company.

Related Laboratory Equipment

Alum preparation and ion tests with Potassium Sulfate commonly involve:

• Aluminum Sulfate — the partner salt that crystallises with it as potash alum.
• Potash Alum — the ready-made double salt, for comparing crystal shape and ion tests.
• Flame Test Of Chemicals Lab Investigation — a structured activity for identifying metal ions by flame colour.
• Barium Chloride 200 g — the reagent that confirms the sulfate ion.
• Porcelain Dish (China Dish) — concentrates the alum solution to its crystallising point.

The Laboratory Equipment category lists more reagents and glassware for these practicals.

Frequently Asked Questions

What is Potassium Sulfate used for in school labs?
Potassium Sulfate is used in school and college labs to prepare potash alum crystals, to show the lilac flame of potassium ions and to practise the barium chloride test for sulfate. It also illustrates fertiliser chemistry as sulfate of potash in agriculture and environmental lessons.

How is potash alum made from Potassium Sulfate?
Potash alum is made by dissolving Potassium Sulfate and aluminium sulfate together in hot water, filtering if needed and letting the solution cool slowly until octahedral crystals separate. Take the exact quantities from your practical manual; aluminium sulfate can be added to the same quotation.

What colour flame does Potassium Sulfate give?
Potassium Sulfate gives a lilac flame, the characteristic colour of potassium ions. Sodium traces can hide it behind a strong yellow, so view the flame through blue cobalt glass and clean the wire loop in concentrated hydrochloric acid before each test.

Is laboratory Potassium Sulfate the same as fertiliser sulfate of potash?
Chemically both are Potassium Sulfate, but this listing is an analytical reagent grade 100 g pack with MSDS, intended for laboratory work and teaching. Fertiliser grades are meant for field use and are not a substitute where reagent purity matters.

What is the shelf life of Potassium Sulfate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is stated for Potassium Sulfate. Ask us for the expiry date of the batch you are quoted and keep the container closed on a dry shelf away from strong acids.

Can Potassium Sulfate be ordered with other reagents for export?
Yes. Potassium Sulfate can be quoted together with aluminium sulfate, barium chloride and glassware for delivery across India and international markets. Send the pack quantities and destination, and Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, will prepare a combined quotation.

Nickel Sulfate (Product Code: SCI-721/317) is an analytical reagent grade nickel(II) salt used to study transition-metal colour, complex-ion formation and electroplating chemistry in senior school and college laboratories. Because nickel compounds can cause skin allergy, it suits supervised practicals where students wear gloves, and each 100 g pack is supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India.

Specifications

What Is Nickel Sulfate Used For?

Nickel Sulfate dissolves to give a green solution of hydrated nickel(II) ions, a clear starting point for lessons on why transition-metal compounds are coloured. Sodium hydroxide then produces a pale green nickel(II) hydroxide precipitate, and excess ammonia solution converts it into a deep blue-violet ammine complex, showing ligand exchange in a single test tube.

In industry, nickel sulfate is a main ingredient of nickel-plating baths, so college electrochemistry courses use it to discuss how metals deposit on a cathode. Its dust is classed as a carcinogen by inhalation and as a skin and respiratory sensitiser. Use small amounts, wear nitrile gloves and goggles, avoid dust and collect all nickel waste separately.

What to Specify When Ordering

• The number of 100 g packs for your practical groups.
• The hydration form, if your experiment or syllabus names one.
• Whether gloves and goggles should be quoted with the reagent.
• The delivery address, in India or overseas.

Supplier

Jain Scientific Equipments Private Limited supplies Nickel Sulfate under its ScienceLab name from Ambala, Haryana, for colleges and schools running transition-metal practicals. Institutions registering a new vendor can record the supplying company's GSTIN 06AAECJ8618A1ZT and Legal Entity Identifier 3358004HRD1JIVXKYX49. Further company information is on the ScienceLab profile page.

• Nickel Chloride — an alternative nickel(II) salt for colour comparisons.
• Ammonium Hydroxide (ammonia water) — forms the blue-violet nickel ammine complex.
• Sodium Hydroxide 500 g — precipitates green nickel(II) hydroxide from the solution.
• Gloves, Nitrile, Orange — protects skin from nickel salts during the practical.
• Safety Goggles — eye protection while handling nickel and ammonia solutions.

Find more reagents in the Laboratory Equipment category.

Frequently Asked Questions

What is Nickel Sulfate used for in chemistry labs?
Nickel Sulfate is used to show the colour of transition-metal ions, to form nickel hydroxide and nickel ammine complexes in ligand-exchange experiments, and to discuss nickel electroplating in college electrochemistry. This listing is an analytical reagent grade 100 g pack with MSDS.

Why is Nickel Sulfate solution green?
Nickel Sulfate solution is green because nickel(II) ions surrounded by water molecules absorb light at the red and violet ends of the spectrum and transmit green. Replacing the water ligands with ammonia changes the light absorbed, which is why the colour shifts to blue-violet.

Is Nickel Sulfate safe for school students?
Nickel Sulfate needs careful handling: it can cause skin allergy and its dust is classed as a carcinogen by inhalation. Many schools keep it for senior or college classes, using small volumes of solution, nitrile gloves, goggles and supervised disposal as the supplied MSDS describes.

Which form of Nickel Sulfate does this listing supply?
This Nickel Sulfate listing (SCI-721/317) is analytical reagent grade in a 100 g pack, but it does not state whether the salt is anhydrous or hydrated. If your method specifies a hydrate, mention it when enquiring so we can confirm the form before quoting.

What is the shelf life of Nickel Sulfate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Nickel Sulfate. Ask us for the expiry date of the batch you are quoted, and store the pack sealed and labelled in a locked chemical cupboard.

What details are needed to quote for Nickel Sulfate?
To quote for Nickel Sulfate we need the number of 100 g packs, any required hydrate and the delivery address in India or abroad. Institutions can also ask Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for its GSTIN and LEI for vendor registration.

Magnesium Sulfate (Product Code: SCI-723/318) is an analytical reagent grade magnesium salt, familiar in hydrated form as Epsom salt, used for crystal growing, water-of-crystallisation calculations and magnesium ion tests in school and college laboratories. Biology departments also use it to supply magnesium in plant-nutrition experiments, and the 100 g pack comes with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools sourcing educational laboratory equipment in India.

Specifications

What Is Magnesium Sulfate Used For?

A quantitative favourite is heating a weighed sample of the hydrated salt in a crucible to constant mass. The mass lost is water of crystallisation, and students calculate how many water molecules each formula unit carries. The hydrated salt also crystallises quickly from a warm saturated solution, giving fine needle-shaped crystals within a single lesson.

For ion tests, sodium hydroxide gives a white magnesium hydroxide precipitate that does not dissolve in excess, which separates magnesium from zinc and aluminium. In biology, dilute solutions add magnesium to nutrient cultures, and leaving it out shows the leaf yellowing of magnesium deficiency, because magnesium sits at the centre of chlorophyll. This is a laboratory reagent, not a product for personal or medicinal use.

What to Specify When Ordering

• Whether you need the anhydrous or a hydrated form, as the listing does not say.
• The number of 100 g packs for chemistry and biology groups combined.
• Whether the separate Magnesium Sulphate listing for biology labs should be quoted as well.
• Your delivery location in India or abroad.

Supplier

Magnesium Sulfate is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and serves chemistry and biology departments with reagents and apparatus. One enquiry can cover this salt together with the crucibles, dishes and trays used in the same practicals. Learn more on the company profile page.

Related Laboratory Equipment

Practicals that use Magnesium Sulfate often draw on these catalogue items:

• Magnesium Sulphate — the same salt listed under the biology range; ask us which suits you.
• Crucible with lid — for heating the hydrated salt to constant mass.
• Petri Dish (Complete) — a shallow dish for growing and viewing needle crystals.
• Hydroponic Tray — grows seedlings in nutrient solutions with and without magnesium.
• Magnesium Chloride — a second magnesium salt for comparing ion tests.

For more chemicals and apparatus, open the Laboratory Equipment category.

Frequently Asked Questions

What is Magnesium Sulfate used for in laboratories?
Magnesium Sulfate is used to grow crystals, to find water of crystallisation by heating to constant mass, to practise magnesium ion tests and to supply magnesium in plant-nutrition experiments. This listing is an analytical reagent grade 100 g pack with MSDS.

Is Magnesium Sulfate the same as Epsom salt?
Epsom salt is the common name for hydrated Magnesium Sulfate. This listing is an analytical reagent pack for laboratory teaching, not a household or medicinal product, and it does not state the hydration form, so confirm the form you need when you enquire.

How do students find the water of crystallisation in Magnesium Sulfate?
Students heat a weighed sample of hydrated Magnesium Sulfate in a crucible, cool and reweigh it, and repeat until the mass stops changing. The mass lost is water; converting both masses to moles gives the number of water molecules per formula unit.

How is magnesium identified in Magnesium Sulfate?
Magnesium in Magnesium Sulfate is identified with sodium hydroxide, which gives a white magnesium hydroxide precipitate that stays insoluble in excess. The sulfate part is confirmed separately with barium chloride solution, giving a white precipitate that does not dissolve in dilute hydrochloric acid.

What is the shelf life of Magnesium Sulfate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is given for Magnesium Sulfate. Ask us for the expiry date of the batch you are quoted, and keep the lid closed because the salt can gain or lose water in open air.

Can Magnesium Sulfate be ordered for both chemistry and biology labs?
Yes. Magnesium Sulfate can be ordered in as many 100 g packs as your chemistry and biology departments need, with delivery across India and international markets. Send the quantity and destination, and Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, will prepare a quotation.

Sodium Sulfate 100 g (Product Code: SCI-725/319) is an analytical reagent grade sodium salt used as a drying agent for organic extracts, as an inert electrolyte in water electrolysis and in sulfate tests in college and school chemistry laboratories. Its neutral, unreactive nature suits any job where a salt must carry current or remove water without joining the reaction, and each 100 g pack comes with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier to institutions.

Specifications

What Is Sodium Sulfate Used For?

In organic practicals, the anhydrous salt is swirled with a wet organic layer after it has been run off from a separating funnel. It takes up dissolved water and clumps together, and once fresh crystals stay free-flowing the solution is dry and can be filtered or decanted. The hydrated form, Glauber's salt, is used instead to discuss water of crystallisation and materials that store heat as they melt and freeze.

In electrolysis, a dilute Sodium Sulfate solution lets water conduct without the salt itself being discharged, so hydrogen collects at the cathode and oxygen at the anode in about a two-to-one volume ratio. A few drops of universal indicator show alkali forming around one electrode and acid around the other. Barium chloride then confirms the sulfate ion with a white precipitate.

What to Specify When Ordering

• Anhydrous (for drying) or the hydrated Glauber's salt form, since the listing does not state which.
• The number of 100 g packs your classes need.
• Whether the separate Sodium Sulfate listing should be quoted alongside.
• The delivery destination, within India or overseas.

Supplier

Jain Scientific Equipments Private Limited supplies Sodium Sulfate 100 g through its ScienceLab brand from Ambala, Haryana, for organic, physical and inorganic chemistry teaching. The company can quote the salt together with separating funnels, flasks and electrolysis apparatus from its catalogue. Company background is on the ScienceLab profile page.

Related Laboratory Equipment

Drying and electrolysis work with Sodium Sulfate 100 g typically involves:

• Sodium Sulfate — a separate catalogue listing of the same salt.
• Separatory Funnel — separates the organic layer before it is dried.
• Conical Flask — holds the organic solution while the drying agent is swirled in.
• Water Electrolysis Apparatus (Hoffman Voltmeter) — collects hydrogen and oxygen from the sodium sulfate electrolyte.
• Universal pH Indicator — reveals the acid and alkali forming at the electrodes.

See the full Laboratory Equipment category for other reagents and glassware.

Frequently Asked Questions

What is Sodium Sulfate 100 g used for?
Sodium Sulfate 100 g is used to dry organic extracts, as an inert electrolyte when electrolysing water, and in sulfate tests and water-of-crystallisation lessons. It is an analytical reagent grade pack supplied with MSDS for school and college chemistry laboratories.

How is Sodium Sulfate used to dry an organic solution?
Anhydrous Sodium Sulfate is added to the wet organic solution and swirled; it absorbs water and forms clumps. Keep adding small portions until some crystals stay loose, wait briefly, then filter or decant the dried liquid. Confirm the anhydrous form when you order.

Why is Sodium Sulfate added to water for electrolysis?
Pure water conducts poorly, so a little Sodium Sulfate is dissolved to carry the current. Its ions are not discharged under normal classroom conditions, leaving hydrogen at the cathode and oxygen at the anode, which is why it is a standard electrolyte for Hofmann-type water electrolysis.

What is the difference between anhydrous Sodium Sulfate and Glauber's salt?
Anhydrous Sodium Sulfate contains no water of crystallisation and works as a drying agent, while Glauber's salt is the decahydrate, which holds water of crystallisation in its crystals. This listing does not state which form the 100 g pack contains, so tell us the form you need.

What is the shelf life of Sodium Sulfate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Sodium Sulfate. Ask us for the expiry date of the batch you are quoted, and keep anhydrous material tightly closed so it does not absorb moisture before use.

Can Sodium Sulfate 100 g be supplied in bulk or for export?
Yes. Sodium Sulfate 100 g can be supplied in multiple packs to schools, colleges and dealers across India and international markets. Share the quantity, form and destination, and Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, will send a quotation.

Zinc Sulfate 100 g (Product Code: SCI-728/320) is an analytical reagent grade zinc salt used as the electrolyte for the zinc half-cell of a Daniell cell, in reactivity-series experiments and in zinc ion tests in school and college chemistry laboratories. It forms colourless solutions that pair clearly with blue copper sulfate when students assemble an electrochemical cell kit in school, and each 100 g pack includes an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Zinc Sulfate Used For?

In the Daniell cell, a zinc plate stands in Zinc Sulfate solution and a copper electrode in copper sulfate solution, the two joined by a salt bridge or porous pot. Zinc gives up electrons more readily than copper, so a voltmeter across the electrodes shows a steady reading that students can relate to the reactivity series.

Displacement tests use the same solution in reverse: a strip of copper left in Zinc Sulfate shows no change, confirming that copper is less reactive than zinc. For ion identification, sodium hydroxide gives a white zinc hydroxide precipitate that redissolves in excess, as does ammonia solution, helping students tell zinc apart from magnesium and aluminium. The salt is harmful if swallowed, can damage the eyes and is toxic to aquatic life, so wear goggles and collect the waste.

What to Specify When Ordering

• The number of 100 g packs for your cell-building groups.
• Whether zinc plates, copper electrodes, copper sulfate or a Daniell cell should be quoted together.
• Any hydration form your method specifies.
• Your delivery address within India or abroad.

Supplier

Zinc Sulfate 100 g is sourced and supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab name in Ambala, Haryana. Physics and chemistry departments can combine it with electrodes and cell apparatus on one enquiry, and dealers can request it with other reagents in the same shipment. Visit the ScienceLab profile page for company details.

Related Laboratory Equipment

Electrochemistry lessons using Zinc Sulfate 100 g commonly include:

• Daniell Cell — the cell apparatus this electrolyte is used in.
• Zinc Plate — the electrode that stands in the zinc sulfate half-cell.
• Hydrated Copper Sulfate 500 g — the electrolyte for the copper half-cell.
• Zinc Sulfate — a separate listing of the same salt; ask us which to order.
• Ammonium Hydroxide (Ammonia) — redissolves zinc hydroxide in the ion test.

More salts and cell apparatus are in the Laboratory Equipment category.

Frequently Asked Questions

What is Zinc Sulfate 100 g used for?
Zinc Sulfate 100 g is used as the zinc half-cell electrolyte in Daniell cells, in displacement experiments on the reactivity series and in qualitative tests for zinc ions. It is an analytical reagent grade pack supplied with MSDS for school and college laboratories.

How is Zinc Sulfate used in a Daniell cell?
In a Daniell cell, Zinc Sulfate solution surrounds the zinc electrode while copper sulfate solution surrounds the copper electrode, with a salt bridge or porous pot between them. Zinc is oxidised, electrons flow through the external circuit to copper, and the cell gives a measurable voltage.

Why does copper not react with Zinc Sulfate solution?
Copper does not react with Zinc Sulfate solution because copper is less reactive than zinc and cannot displace it. Zinc placed in copper sulfate does react, so running both tests side by side gives students clear evidence for the order of the reactivity series.

How are zinc ions identified in Zinc Sulfate?
Zinc ions in Zinc Sulfate give a white precipitate with sodium hydroxide that dissolves again in excess, and the same happens with excess ammonia solution. Together these two results distinguish zinc from magnesium and aluminium during qualitative salt analysis.

What is the shelf life of Zinc Sulfate?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is stated for Zinc Sulfate. Ask us for the expiry date of the batch you are quoted, and store the pack closed in a cool, dry cabinet away from food and drink.

Can Zinc Sulfate 100 g be ordered with Daniell cell apparatus?
Yes. Zinc Sulfate 100 g can be quoted together with a Daniell cell, zinc plates, copper electrodes and copper sulfate for delivery across India and international markets. Send your list and destination to Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for a combined quotation.

Sulfocianur Ammonium (Product Code: SCI-731/321), also known as ammonium thiocyanate or ammonium sulfocyanide, is an analytical reagent grade salt used to detect iron(III) ions and to demonstrate endothermic processes in school and college chemistry laboratories. It comes as a 100 g pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which stocks it as a lab chemicals supplier in India and for international buyers.

Specifications

What Is Sulfocianur Ammonium Used For?

Its best-known use is the thiocyanate test for iron(III): a few drops of the solution turn any liquid containing iron(III) ions blood-red, sensitive enough to reveal traces of iron in water samples or dissolved rust. Iron(II) gives no strong colour until it is oxidised, so the same test helps students tell the two oxidation states of iron apart.

Ammonium thiocyanate dissolves in water with a noticeable fall in temperature, and when the dry salt is mixed with solid barium hydroxide octahydrate the reaction absorbs so much heat that a wet beaker can freeze to a wooden board — a memorable endothermic demonstration for the teacher to run in a ventilated room, because ammonia is released. In analytical chemistry it is also the titrant in Volhard's method for silver, with an iron(III) salt as the indicator.

What to Specify When Ordering

• The number of 100 g packs each laboratory needs.
• The main use (iron(III) test, endothermic demonstration or Volhard titration), so matching reagents can be quoted.
• That the ammonium salt is the one you want, because potassium and sodium thiocyanate are listed separately.
• Companion items such as an iron(III) salt for practising the red colour test.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies Sulfocianur Ammonium from Ambala in 100 g packs with the MSDS to schools, colleges and analytical laboratories. Institutional buyers who need vendor registration details can use the company's CIN U29309HR2020PTC087597 and GSTIN 06AAECJ8618A1ZT. Thiocyanate salts, iron salts and glassware for the same practical can go on one quotation for institutions, dealers and importers in India and international markets, and the ScienceLab profile gives more background.

Frequently Asked Questions

Is Sulfocianur Ammonium the same as ammonium thiocyanate?
Yes. Sulfocianur Ammonium SCI-731/321 is ammonium thiocyanate, also called ammonium sulfocyanide in older texts. It is supplied as a 100 g analytical reagent pack with its MSDS for iron(III) tests, endothermic demonstrations and thiocyanate titrations.

How is Sulfocianur Ammonium used to test for iron(III)?
Dissolve a little Sulfocianur Ammonium in water and add a few drops to the test solution: a blood-red colour shows iron(III) ions. Iron(II) gives no strong colour until it is oxidised, so the test also distinguishes the two oxidation states of iron.

Why does Sulfocianur Ammonium get cold when dissolved?
Dissolving Sulfocianur Ammonium in water absorbs heat from the surroundings, so the solution becomes noticeably cold. The effect is far stronger when the dry salt reacts with solid barium hydroxide octahydrate, a classic endothermic demonstration done in a ventilated room because ammonia is released.

How should Sulfocianur Ammonium be stored?
Keep Sulfocianur Ammonium SCI-731/321 tightly closed in a cool, dry place, because the salt absorbs moisture, and away from acids and oxidising agents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

Who supplies Sulfocianur Ammonium SCI-731/321?
Sulfocianur Ammonium SCI-731/321 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and provides it with its MSDS to schools, colleges, analytical laboratories, dealers and importers in India and international markets.

Potassium Sulfocyanur (Product Code: SCI-733/322), better known as potassium thiocyanate (KSCN), is an analytical reagent grade salt used to demonstrate chemical equilibrium and to detect iron(III) in school and college chemistry laboratories. Supplied as a 100 g pack with its MSDS, it is the thiocyanate commonly used for the iron(III)–thiocyanate equilibrium experiment. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, together with the chemistry lab equipment such practicals need.

Specifications

What Is Potassium Sulfocyanur Used For?

Mixing dilute iron(III) chloride with potassium thiocyanate gives a blood-red complex in equilibrium with the pale starting ions, so students can watch Le Chatelier's principle at work: adding more thiocyanate or more iron(III) deepens the colour, while adding silver nitrate, which removes thiocyanate as a white precipitate, makes it fade. Splitting one red solution across a row of test tubes and changing one condition in each makes an efficient class practical.

In quantitative analysis, potassium thiocyanate is the titrant in Volhard's method: chloride in a sample is precipitated with a measured excess of silver nitrate, and the leftover silver is titrated with thiocyanate until an iron(III) indicator turns red. The same red colour gives a quick qualitative check for iron(III) in water or dissolved rust. Keep the salt away from acids and wear gloves when making up solutions.

What to Specify When Ordering

• The number of 100 g packs each laboratory needs.
• Whether it is for equilibrium practicals, iron tests or Volhard titrations, so the right companion reagents are quoted.
• That potassium thiocyanate is the salt you want, since ammonium and sodium thiocyanate are listed separately.
• Companion reagents such as iron(III) chloride and silver nitrate for the same enquiry.

Supplier

ScienceLab, the brand of Jain Scientific Equipments Private Limited in Ambala, supplies Potassium Sulfocyanur in 100 g packs with the MSDS for equilibrium, analysis and inorganic chemistry practicals.

Frequently Asked Questions

Is Potassium Sulfocyanur the same as potassium thiocyanate?
Yes. Potassium Sulfocyanur SCI-733/322 is potassium thiocyanate, KSCN, sometimes called potassium sulfocyanide. It is supplied as a 100 g analytical reagent pack with its MSDS for equilibrium practicals, iron(III) tests and Volhard titrations in school and college laboratories.

How does Potassium Sulfocyanur demonstrate Le Chatelier's principle?
Potassium Sulfocyanur forms a blood-red complex with iron(III) that exists in equilibrium with the separate ions. Adding more thiocyanate or iron(III) deepens the red, while adding silver nitrate removes thiocyanate and makes the colour fade, showing how an equilibrium responds to changes.

What is Volhard's method with Potassium Sulfocyanur?
In Volhard's method, chloride is precipitated with a known excess of silver nitrate and the unused silver is titrated with Potassium Sulfocyanur solution. An iron(III) indicator turns red at the end point, allowing the chloride content of the sample to be calculated.

How should Potassium Sulfocyanur be stored?
Keep Potassium Sulfocyanur SCI-733/322 tightly closed in a dry place, away from acids and strong oxidisers, as it takes up moisture from the air. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
