Sodium Ethanoate (Product Code: SCI-400/167) is an analytical reagent grade sodium salt of ethanoic acid, also called sodium acetate, used to prepare buffer solutions and to study salt hydrolysis and crystallisation in school and college chemistry laboratories. Teachers and practical-store managers order it as a 200 g pack supplied with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

Specifications

What Is Sodium Ethanoate Used For?

Mixed with ethanoic acid, sodium ethanoate makes an acetate buffer, the standard example for showing students how a solution resists a change in pH when a few drops of acid or alkali are added. On its own it dissolves to give a mildly alkaline solution, because the ethanoate ion is the conjugate base of a weak acid, so testing it with universal indicator beside a neutral salt demonstrates salt hydrolysis clearly.

It is also the salt behind the supersaturated-solution or hot ice demonstration: a hot, concentrated solution cooled without disturbance stays liquid until a seed crystal is added, then crystallises within seconds and feels warm, proving that crystallisation releases heat. That makes it a natural choice for a crystallization kit in school science clubs, and in organic chemistry heating sodium ethanoate with soda lime is the traditional laboratory route to methane.

Benzene (Product Code: SCI-403/168) is an analytical reagent grade aromatic hydrocarbon used as a reference compound and non-polar solvent in college and senior-school organic chemistry laboratories. It is listed with a capacity of 250 ml, comes with its MSDS and is intended for supervised work in a fume cupboard, because benzene is highly flammable and harmful to health. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Benzene Used For?

In organic chemistry teaching, benzene is the parent aromatic compound. Students compare its ring structure with that of alkenes, discuss why it prefers substitution to addition reactions, and use it as a reference liquid when aromatic properties are studied. Being colourless, immiscible with water and less dense than water, it forms a separate upper layer in a separating funnel, and iodine dissolves in it far more readily than in water, a clear example of like dissolving like.

Benzene is a recognised carcinogen and is highly flammable, so it should live in a ventilated flammables or chemistry reagent cabinet and be dispensed only inside a working school or college fume cupboard, with goggles and chemical-resistant gloves. Many schools restrict it to teacher demonstrations or use a less hazardous solvent for student practicals, so check your syllabus and local safety rules before ordering.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, sources Benzene for colleges, universities and senior-school chemistry departments and supplies it with its MSDS. Because benzene is a flammable liquid, share the delivery address early so that suitable packing and transport can be confirmed for destinations in India and international markets. Company background is on the ScienceLab profile.

Ammonium Sulfate (Product Code: SCI-405/169) is an analytical reagent grade ammonium salt used for salt-analysis practice, fertiliser chemistry and protein precipitation in school, college and biology laboratories. It comes in a 200 g pack with its MSDS, a straightforward addition for chemistry teachers assembling a salt analysis kit for school practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Ammonium Sulfate Used For?

Ammonium sulfate is a common unknown in qualitative analysis because both of its ions give clean, visible results. Warming a little of the salt with sodium hydroxide releases ammonia, recognised by its sharp smell and by turning damp red litmus paper blue. Its solution gives a white precipitate with barium chloride that does not dissolve in dilute hydrochloric acid, which confirms the sulfate.

Agriculture and environmental science lessons use it as an example of a nitrogen and sulphur fertiliser, and to explain why heavy use of ammonium fertilisers tends to make soil more acidic. In biology and biochemistry, concentrated ammonium sulfate solution is used to salt out proteins such as egg albumin, a simple first step in protein purification. Store it away from strong alkalis, since the two together release ammonia.

What to Specify When Ordering

• How many 200 g packs each laboratory or store needs.
• The main use (salt analysis, fertiliser demonstrations or protein work), so we can check the reagent suits your method.
• Companion items for the same enquiry, such as sodium hydroxide, red litmus paper or barium chloride.
• The product code you want, because the catalogue also has a separate Ammonium Sulfate 200 g listing.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, sources Ammonium Sulfate for chemistry, agriculture and biology laboratories and sends it in 200 g packs with the MSDS. As a lab consumables supplier in India, the company can combine it with litmus paper, glassware and other reagents on one quotation for schools, colleges, dealers and importers in India and international markets. More about the company is on the ScienceLab profile.

Related Laboratory Equipment

Find more chemicals in Laboratory Equipment.

Frequently Asked Questions

How do you test Ammonium Sulfate for the ammonium ion?
To test Ammonium Sulfate for the ammonium ion, warm a small sample with sodium hydroxide solution in a test tube. Ammonia gas is released, which smells sharp and turns damp red litmus paper blue; carry out the test in a well-ventilated area.

Can Ammonium Sulfate be used for protein precipitation?
Yes. Ammonium Sulfate is widely used to salt out proteins, because high salt concentrations lower protein solubility. Ammonium Sulfate SCI-405/169 is analytical reagent grade in a 200 g pack, so tell us the amount your method uses and we will quote the right number of packs.

Is Ammonium Sulfate SCI-405/169 a field fertiliser?
No. Ammonium Sulfate SCI-405/169 is an analytical reagent for laboratory teaching and analysis, not a bulk field fertiliser. Schools and colleges use it to demonstrate how nitrogen fertilisers behave in soil and water, working from its 200 g pack and MSDS.

How should Ammonium Sulfate be stored?

Hydrated Copper Sulfate (Product Code: SCI-406/170) is an analytical reagent grade copper(II) sulfate containing water of crystallisation, used for dehydration, displacement, crystal-growing and electroplating experiments in school and college chemistry laboratories. It comes in a 200 g pack with its MSDS for the copper sulphate crystal practicals that school syllabuses include. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Hydrated Copper Sulfate Used For?

Heating a few crystals in a dry boiling tube drives off the water of crystallisation: the blue solid turns white, droplets condense near the mouth of the tube, and adding water back restores the blue colour with noticeable warming. The same reversible change is why white anhydrous copper sulfate serves as a simple chemical test for water.

Dissolved in water, it gives the blue solution for the displacement activity in which an iron nail becomes coated with reddish-brown copper while the solution fades to pale green, showing that iron is more reactive than copper. Teachers also grow large blue crystals from a saturated solution and use it as the electrolyte for copper electroplating. It is harmful if swallowed and toxic to aquatic life, so collect waste solutions instead of pouring them down the sink.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, sources Hydrated Copper Sulfate as an analytical reagent and supplies it in 200 g packs with the MSDS. Schools and colleges that buy chemistry lab equipment in India from ScienceLab can add the reagent to the same order as burners, electrodes and glassware, and dealers and importers in international markets can request it the same way. The ScienceLab profile has more about the company.

• Hydrated Copper Sulfate 500 g — the larger pack of the same reagent.
• Glass Spirit Lamp — gentle heat for driving off the water of crystallisation.
• Electrodes, Copper — for electroplating and electrolysis in the blue solution.
• Voltameter, Copper — measures the copper deposited during electrolysis.
• Granulated Zinc (granules) — displaces copper from the solution in reactivity tests.

See more reagents and apparatus in Laboratory Equipment.

Frequently Asked Questions

What happens when Hydrated Copper Sulfate is heated?
When Hydrated Copper Sulfate is heated gently, it loses its water of crystallisation and changes from blue to white anhydrous copper sulfate. Adding water turns it blue again and releases heat; heat only small amounts in a dry tube pointed away from people.

How is hydrated copper sulfate different from the anhydrous form?
Hydrated Copper Sulfate contains water of crystallisation and is blue, while anhydrous copper sulfate is a white powder with that water removed. Hydrated Copper Sulfate SCI-406/170 is the hydrated form, supplied as an analytical reagent in a 200 g pack with its MSDS.

Can Hydrated Copper Sulfate be used to grow crystals?
Yes. Hydrated Copper Sulfate is widely used for crystal growing: dissolve it in warm water until no more dissolves, filter, then let the solution cool and evaporate slowly with a seed crystal hung on a thread. Keep the setup covered and away from younger children.

How should Hydrated Copper Sulfate be stored?
Store Hydrated Copper Sulfate SCI-406/170 in a closed container in a cool place, away from food and from strong heat that would drive off its water. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

Can Hydrated Copper Sulfate be ordered in quantity or exported?
Yes. Hydrated Copper Sulfate SCI-406/170 can be quoted in several 200 g packs for school stores, colleges and dealers, and for buyers in international markets. A larger-pack listing is also in the catalogue if your laboratory uses more of the reagent.

Who supplies Hydrated Copper Sulfate SCI-406/170?

Ferrous Sulfate (II) (Product Code: SCI-408/171) is an analytical reagent grade iron(II) sulfate used for decomposition, redox and ion-identification experiments in school and college chemistry laboratories. It is sold in a 200 g pack with its MSDS for teachers who need a source of iron(II) ions for class practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Ferrous Sulfate Used For?

A well-known decomposition activity starts with ferrous sulfate crystals heated in a dry boiling tube. They first lose their water of crystallisation, then break down to a reddish-brown iron(III) oxide residue while sulphur oxides with a smell of burning sulphur are given off. Because those gases irritate the airways, the heating belongs in a fume cupboard or a well-ventilated school chemistry lab.

In solution it supplies iron(II) ions for analysis. Sodium hydroxide gives a dirty-green precipitate that turns brown as air oxidises it, and a freshly made solution decolourises acidified potassium permanganate, a clear introduction to redox titration. A fresh ferrous sulfate solution is also needed for the brown ring test for nitrates, because the solution slowly oxidises on standing.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which sources Ferrous Sulfate (II) for schools, colleges and analytical laboratories and ships each 200 g pack with its MSDS. Institutional and tender buyers completing vendor registration can use the supplying company's GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49.

• Ferrous Sulfate (II) 100 g — a smaller pack of the same reagent.
• Potassium Permanganate — decolourised by iron(II) ions in redox work.
• Ferrous Ammonium sulphate — an iron(II) salt that resists air oxidation better in titrations.
• Sodium Hydroxide — produces the green iron(II) hydroxide precipitate.
• Bunsen Burner — heat source for decomposing the crystals.

More chemicals and apparatus are in Laboratory Equipment.

Frequently Asked Questions

What happens when Ferrous Sulfate (II) is heated?
When Ferrous Sulfate (II) crystals are heated, they first lose water of crystallisation and then decompose, leaving reddish-brown iron(III) oxide and releasing sulphur dioxide and sulphur trioxide. It is a standard example of a decomposition reaction; heat only in a ventilated area or fume cupboard.

Why does Ferrous Sulfate (II) solution turn yellow-brown?
Ferrous Sulfate (II) solution turns yellow-brown because air slowly oxidises iron(II) ions to iron(III). Prepare solutions of Ferrous Sulfate (II) SCI-408/171 fresh for each practical, keep the solid tightly closed, and add a little dilute sulfuric acid to slow the change.

Is Ferrous Sulfate (II) the same as iron(II) sulfate?
Yes. Ferrous Sulfate (II) is iron(II) sulfate, often simply called ferrous sulphate, since ferrous already means iron in the +2 state. Ferrous Sulfate (II) SCI-408/171 is analytical reagent grade and comes in a 200 g pack with its MSDS.

How should Ferrous Sulfate (II) be stored?
Keep Ferrous Sulfate (II) SCI-408/171 tightly closed in a cool, dry cabinet, out of direct sunlight and away from oxidising agents, to limit air oxidation. 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 Ferrous Sulfate (II) SCI-408/171?
Ferrous Sulfate (II) SCI-408/171 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and sends it with its MSDS to schools, colleges, analytical laboratories and dealers in India and international markets.

What should a Ferrous Sulfate (II) enquiry include?

Sodium Sulfate (Product Code: SCI-430/172) is an analytical reagent grade sodium salt used as a neutral electrolyte in water electrolysis, as a sulfate source in analysis and, in its anhydrous form, as a drying agent for organic liquids in school and college laboratories. Lab technicians and chemistry teachers receive it in a 200 g pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

Specifications

What Is Sodium Sulfate Used For?

Pure water conducts electricity poorly, so a little sodium sulfate is dissolved in it before electrolysis in a Hoffman voltameter. The salt carries the current without being used up: hydrogen collects at the cathode and oxygen at the anode in a two-to-one volume ratio, and a few drops of universal indicator reveal alkali forming around one electrode and acid around the other.

Because it comes from a strong acid and a strong base, its solution is close to neutral, which makes it the control salt when students compare the pH of different salt solutions. In organic practicals the anhydrous form is swirled into a wet organic layer after separation in a separating funnel, where it takes up dissolved water and clumps until the liquid is dry. Its solution also gives the white barium sulfate precipitate in the sulfate test.

What to Specify When Ordering

• Whether you need the anhydrous form for drying organic liquids, so we can confirm the form of the batch offered.
• The number of 200 g packs for each laboratory.
• Companion apparatus, such as a water electrolysis apparatus or separating funnel, for the same quotation.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab, sources Sodium Sulfate for school, college and technical-training laboratories and supplies it in 200 g packs with the MSDS. The same enquiry can include electrolysis apparatus, separating funnels and indicators, which helps a department restock several practicals at once, in India or in international markets. See the ScienceLab profile for company details.

• Conical Flask — holds the organic liquid while the drying agent is swirled in.
• Sodium Sulfate 100 g — a smaller pack of the same salt.

Browse the wider range in Laboratory Equipment.

Frequently Asked Questions

Why is Sodium Sulfate added to water for electrolysis?
Sodium Sulfate is added because pure water conducts electricity poorly. Its ions carry the current while the water itself is split into hydrogen and oxygen, and the sodium and sulfate ions stay in solution, so the gases collected come from the electrolysis of water.

Can Sodium Sulfate SCI-430/172 be used as a drying agent?
Sodium Sulfate dries organic liquids only in its anhydrous form. The listing for Sodium Sulfate SCI-430/172 states analytical reagent grade and a 200 g pack but not the hydration state, so ask us to confirm the form before ordering it for drying work.

Is Sodium Sulfate solution neutral?
Yes, a Sodium Sulfate solution is close to neutral, because the salt is formed from a strong acid, sulfuric acid, and a strong base, sodium hydroxide. That makes it a useful reference when students compare acidic, neutral and alkaline salt solutions.

How should Sodium Sulfate be stored?
Keep Sodium Sulfate SCI-430/172 tightly closed in a dry cabinet, because moisture from the air can make the salt cake. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

Is Sodium Sulfate available in a smaller pack?
Yes. Besides Sodium Sulfate SCI-430/172 in a 200 g pack, the catalogue lists Sodium Sulfate in a smaller pack under its own code, which suits laboratories that use only occasional amounts. State the code you want in your enquiry.

Who supplies Sodium Sulfate SCI-430/172?
Sodium Sulfate SCI-430/172 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and delivers it with its MSDS to schools, colleges, training institutes and dealers in India and international markets.

Zinc Sulfate (Product Code: SCI-411/173) is an analytical reagent grade zinc salt used as the electrolyte of the zinc half-cell in Daniell cell experiments and for reactivity and ion tests in school and college chemistry laboratories. It is packed as 200 g with its MSDS, ready to sit alongside an electrochemical cell kit for school practicals. 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, with a salt bridge or porous pot joining the two. Zinc atoms give up electrons and pass into solution while copper deposits on the other electrode, and a voltmeter across the plates shows a chemical reaction producing electricity.

The salt also completes the reactivity-series activity: a copper strip left in zinc sulfate solution stays unchanged, whereas zinc placed in copper sulfate soon turns coppery. For the zinc-ion test, sodium hydroxide or ammonia solution gives a white precipitate that redissolves in excess, and biology classes can use it when studying zinc as a plant micronutrient. Wear goggles, as the salt irritates the eyes, and collect used solutions because zinc compounds harm aquatic life.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is a lab chemicals supplier in India that sources Zinc Sulfate and sends each 200 g pack with its MSDS. Chemistry and physics departments building electrochemistry practicals can request the salt together with zinc plates, copper electrodes and copper sulfate, and dealers and importers in international markets can do the same. The ScienceLab profile describes the company.

Related Laboratory Equipment

Items for building a zinc and copper cell around this salt:

• Daniell Cell — the cell in which zinc sulfate forms the zinc half-cell.
• Zinc Plate — the electrode that stands in the zinc sulfate solution.
• Hydrated Copper Sulfate — the electrolyte for the copper half-cell.
• Student Voltaic Cell Set — for comparing the voltage of different metal pairs.
• Zinc Sulfate 100 g — a smaller pack of the same salt.

More items are listed under Laboratory Equipment.

Frequently Asked Questions

How is Zinc Sulfate used in a Daniell cell?
In a Daniell cell, Zinc Sulfate solution surrounds the zinc electrode while copper sulfate surrounds the copper electrode, and a salt bridge links them. Zinc dissolves as ions and copper deposits, producing a measurable voltage; Zinc Sulfate SCI-411/173 comes in a 200 g pack for this work.

Does copper react with Zinc Sulfate solution?
No. Copper placed in Zinc Sulfate solution shows no change, because copper is less reactive than zinc and cannot displace it. The contrast with zinc in copper sulfate, which becomes coated with copper, is a standard reactivity-series demonstration.

How do you test Zinc Sulfate for zinc ions?
Add sodium hydroxide solution drop by drop to a Zinc Sulfate solution: a white zinc hydroxide precipitate forms and then dissolves in excess. Ammonia solution behaves the same way, which helps distinguish zinc from aluminium, whose precipitate does not dissolve in excess ammonia.

How should Zinc Sulfate be stored?
Store Zinc Sulfate SCI-411/173 in its closed container in a cool, dry place, away from food and from drains. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

Can Zinc Sulfate be quoted with electrochemistry apparatus?
Yes. Zinc Sulfate SCI-411/173 can be quoted together with a Daniell cell, zinc plates, copper electrodes and copper sulfate from ScienceLab, so a complete electrochemistry practical arrives on one order. List each item and the number of 200 g packs in your enquiry.

Sodium Thiosulfate (Product Code: SCI-415/174) is an analytical reagent grade sodium salt used for rate-of-reaction experiments with dilute acid and for iodine titrations in school and college chemistry laboratories. It comes in a 100 g pack with its MSDS, a compact quantity for a titration kit in school or college practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Sodium Thiosulfate Used For?

The disappearing-cross experiment is the usual way to study reaction rate. Sodium thiosulfate solution is poured into a flask standing over a cross drawn on paper, dilute hydrochloric acid is added, and students time how long the cross takes to vanish behind the cloudy yellow sulphur that forms. Repeating the run at other concentrations or temperatures shows how each factor speeds up the reaction.

In volumetric analysis, a standardised thiosulfate solution is run from a burette into iodine released in iodometric determinations, with starch indicator turning blue-black until the end point, when the colour disappears sharply. That makes it a core reagent in a volumetric analysis kit for colleges. The salt is also known as hypo from its long use as a photographic fixer, and because the acid reaction gives off some sulphur dioxide, rate experiments belong in a ventilated room.

What to Specify When Ordering

• The number of 100 g packs for each laboratory.
• Whether the salt is for rate experiments, iodine titrations or both, so the quotation can include matching reagents.
• Companion items such as hydrochloric acid, soluble starch, potassium iodide or burettes.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which sources Sodium Thiosulfate for chemistry laboratories and supplies each 100 g pack with its MSDS. Colleges setting up titration benches can add burettes, conical flasks, starch and potassium iodide to the same enquiry, and the company serves schools, dealers and importers in India and international markets. Company information is on the ScienceLab profile.

Related Laboratory Equipment

Reagents and glassware for thiosulfate rate experiments and iodometric titrations:

• Hydrochloric Acid — reacts with thiosulfate in the disappearing-cross experiment.
• Soluble Starch — the indicator for the iodine end point.
• Potassium Iodide — releases the iodine that thiosulfate titrates.
• Burette — delivers the thiosulfate solution during titration.
• Sodium Thiosulphate(Thio) — another listing of the salt in a different pack.

Explore further in Laboratory Equipment.

Frequently Asked Questions

What is the disappearing cross experiment with Sodium Thiosulfate?
It is a rate-of-reaction experiment in which Sodium Thiosulfate solution reacts with dilute hydrochloric acid to form a cloudy sulphur precipitate. Students time how long a cross under the flask takes to disappear, then repeat at different concentrations or temperatures to compare rates.

Why is Sodium Thiosulfate used in iodine titrations?
Sodium Thiosulfate reacts quickly and completely with iodine, reducing it to colourless iodide, so it measures how much iodine a reaction has released. Starch indicator marks the end point when the blue-black colour disappears, and the thiosulfate solution should be standardised before accurate work.

How much Sodium Thiosulfate is in one pack?
Each pack of Sodium Thiosulfate SCI-415/174 contains 100 g of analytical reagent grade salt and is supplied with its MSDS. Tell us how many packs your laboratories need in your enquiry, and we will quote that number of packs.

Is hypo the same as Sodium Thiosulfate?
