What Is Sulfur Powder Used For?
Sulfur powder is the classic starting material for the iron and sulfur experiment, in which students compare a mixture of the two elements, still separable with a magnet, with the black iron sulfide compound formed on heating. Gently melting the powder shows its changes of colour and runniness, and pouring the hot melt into cold water gives rubbery plastic sulfur, one of its allotropic forms. It is a standard entry on school chemistry lab equipment lists in India for these element-and-compound practicals.
Burning a small amount in a deflagrating spoon inside a gas jar gives a blue flame and sulfur dioxide, which dissolves in water to form an acidic solution, so this demonstration belongs in a fume cupboard. Sulfur also dissolves in carbon disulfide, and rhombic crystals appear as the solvent evaporates. Keep the powder away from flames and oxidising agents, because it is a flammable solid.
What to Specify When Ordering
- The number of 100 g packs each laboratory needs.
- The practicals you plan (iron and sulfur, plastic sulfur, combustion), so companion reagents and apparatus can be quoted.
- Companion items such as iron powder, a magnet or carbon sulfide for the same enquiry.

| Product code | SCI-696/306 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Ammonium Sulfate 200 g Used For?
Ammonium sulfate is one of the two salts needed to prepare ferrous ammonium sulfate (Mohr's salt): equal molar amounts of ammonium sulfate and iron(II) sulfate are dissolved in warm water acidified with a little dilute sulfuric acid, and pale green crystals form as the solution cools. Using aluminium sulfate instead gives ammonium alum, so this one reagent supports several double-salt preparations at senior secondary and college level.
Its solution is slightly acidic because the ammonium ion reacts with water, which makes it a clear example in salt-hydrolysis lessons when tested with indicator alongside neutral and alkaline salts. Students can also make ammonium sulfate themselves by neutralising ammonia solution with dilute sulfuric acid and crystallising the product, then compare their crystals with this reagent-grade sample, a good exercise for crystallisation kits in school practicals.
What to Specify When Ordering
- The code SCI-696/306 and the number of 200 g packs, because the catalogue also has a separate Ammonium Sulfate listing.
- The practical you plan (Mohr's salt, ammonium alum or hydrolysis tests), so companion salts can be quoted.
- Companion reagents such as iron(II) sulfate or aluminium sulfate for the same enquiry.
Supplier
Jain Scientific Equipments Private Limited trades as ScienceLab and supplies Ammonium Sulfate 200 g from Ambala, packed with the MSDS, to schools, colleges and teacher-training laboratories.

Frequently Asked Questions
How is Mohr's salt prepared with Ammonium Sulfate 200 g?
To prepare Mohr's salt, dissolve equal molar amounts of Ammonium Sulfate 200 g (SCI-696/306) and iron(II) sulfate in warm water containing a little dilute sulfuric acid, then let the solution cool slowly. Pale green crystals of ferrous ammonium sulfate form and can be filtered off and dried.
Why is an Ammonium Sulfate solution slightly acidic?
An Ammonium Sulfate solution is slightly acidic because ammonium ions react with water and release a small amount of hydrogen ions. Testing Ammonium Sulfate 200 g with universal indicator beside sodium chloride and sodium carbonate solutions makes this salt-hydrolysis point clear to students.
How is Ammonium Sulfate 200 g different from the other Ammonium Sulfate listing?
Ammonium Sulfate 200 g (SCI-696/306) and the separate Ammonium Sulfate listing are both analytical reagent grade in 200 g packs with MSDS, each under its own product code. State the code you want on your enquiry so the quotation matches your purchase records.
How should Ammonium Sulfate 200 g be stored?
Keep Ammonium Sulfate 200 g (SCI-696/306) tightly closed in a cool, dry cabinet away from strong alkalis, which release ammonia from it. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

| Product code | SCI-699/308 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Carbon Sulfide Used For?
In school chemistry, carbon disulfide is best known as the solvent that separates the iron and sulfur mixture: it dissolves the sulfur and leaves the iron behind, while the compound iron sulfide does not dissolve at all. Letting a sulfur solution evaporate slowly in a fume cupboard leaves well-formed rhombic sulfur crystals, a standard way to show one of sulfur's allotropes.
Iodine dissolves in it to give a violet solution, which shows how non-polar solutes prefer non-polar solvents and supports solvent-extraction exercises with a separating funnel. The liquid is extremely flammable, and its vapour can be ignited by a hot surface such as a hot plate or steam pipe, not only by a flame. Use small volumes in a fume cupboard with all heat sources switched off, and keep the bottle in a ventilated flammables or chemistry reagent cabinet.
What to Specify When Ordering
- The number of 100 ml packs; a highly flammable solvent is best kept in small stocks.
- The intended use (mixture separation, sulfur recrystallisation or iodine extraction), so we can check the reagent suits your method.
- Whether cyclohexane could serve instead for your iodine-extraction exercises, so both can be quoted for comparison.

Frequently Asked Questions
Is Carbon Sulfide the same as carbon disulfide?
Yes. Carbon Sulfide SCI-699/308 is the reagent chemists usually call carbon disulfide (CS2), a volatile liquid used as a solvent for sulfur, iodine, fats and waxes. It is supplied as a 100 ml analytical reagent pack with its MSDS.
What is Carbon Sulfide used for in school chemistry?
Carbon Sulfide SCI-699/308 dissolves sulfur, so it separates sulfur from iron in the mixture-versus-compound practical and lets rhombic sulfur crystallise as it evaporates. It also dissolves iodine to a violet solution for solvent-extraction exercises, always in small volumes inside a fume cupboard.
Why is Carbon Sulfide handled in a fume cupboard?
Carbon Sulfide gives off a toxic, extremely flammable vapour that can ignite on contact with hot surfaces, not only open flames. Use the SCI-699/308 reagent in a fume cupboard, switch off nearby hot plates and burners, and follow the MSDS supplied with the 100 ml pack.
How should Carbon Sulfide be stored?

| Product code | SCI-701/309 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Ammonium Sulfide Used For?
In the classical scheme of cation analysis, sulfide in ammoniacal solution precipitates the zinc, manganese, nickel and cobalt group once the earlier groups have been removed, and ammonium sulfide is a convenient way to supply it. The precipitate colours guide identification: zinc sulfide is white, manganese sulfide is buff to pink, and nickel and cobalt sulfides are black.
Ammonium sulfide solutions slowly turn yellow on standing as polysulfide forms, and yellow ammonium sulfide is used to separate the arsenic, antimony and tin sulfides, which dissolve in it, from copper-group sulfides, which do not. The solution smells strongly of hydrogen sulfide and ammonia, so dispense it only in a fume cupboard and keep the bottle tightly stoppered between uses.
What to Specify When Ordering
- The number of 100 ml packs, remembering that the solution slowly changes on standing, so smaller, fresher stocks work better.
- The other group reagents you need, such as ammonium chloride and ammonia solution, so the analysis set is quoted together.
- Safety items for the same enquiry, such as chemical-resistant gloves.
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, supplies Ammonium Sulfide from Ambala to school, college and university chemistry departments in 100 ml packs with the MSDS. Qualitative analysis needs a whole family of group reagents, and the company can quote them together for institutions, dealers and importers in India and international markets. The company profile explains more about ScienceLab.
Related Laboratory Equipment
Group reagents, test salts and protection used alongside ammonium sulfide:
- Ammonium Chloride — used with ammonia solution to set the buffered conditions for group precipitation.
- Ammonium Hydroxide (Ammonia) — makes the test solution ammoniacal before the sulfides are precipitated.
- Zinc Chloride — a known zinc salt for practising the white zinc sulfide test.
- Nickel Chloride — a reference salt that gives black nickel sulfide.
- Gloves - Protective disposable — chemical-resistant gloves for dispensing group reagents.
More reagents are listed in Laboratory Equipment.
Frequently Asked Questions
Which cations does Ammonium Sulfide precipitate?
In ammoniacal solution, Ammonium Sulfide SCI-701/309 precipitates the sulfides of zinc (white), manganese (buff to pink), nickel and cobalt (both black) once the earlier analytical groups have been removed. These colours guide students to the confirmatory test for each cation.
Why does Ammonium Sulfide turn yellow?
Ammonium Sulfide solution slowly turns yellow on standing as air oxidises some sulfide to polysulfide. Yellow ammonium sulfide still has uses, such as dissolving arsenic, antimony and tin sulfides, but keeping the SCI-701/309 bottle tightly closed slows the change.
How should Ammonium Sulfide be stored?
Keep Ammonium Sulfide SCI-701/309 tightly stoppered in a cool, ventilated cabinet away from acids, which release hydrogen sulfide from it. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Can Ammonium Sulfide be used on an open bench?
Ammonium Sulfide releases hydrogen sulfide and ammonia, both irritating and harmful gases, so dispense the SCI-701/309 reagent in a fume cupboard or a strongly ventilated area. Wear goggles and gloves and follow the MSDS supplied with each 100 ml pack.
Who supplies Ammonium Sulfide SCI-701/309?
Ammonium Sulfide SCI-701/309 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and ships it with its MSDS to schools, colleges, universities, dealers and importers in India and international markets.

| Product code | SCI-703/310 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Sodium Sulfide Used For?
A few drops of sodium sulfide solution precipitate coloured sulfides from many metal salt solutions — black with lead and copper, white with zinc and yellow with cadmium — which makes it a quick way to show insoluble-salt formation and how heavy metals can be detected in water. Adding dilute hydrochloric acid to a small amount releases hydrogen sulfide, which blackens lead acetate paper; this demonstration belongs strictly in a fume cupboard.
Sodium sulfide is also the usual sample for identifying the sulfide ion: with freshly prepared sodium nitroprusside solution it gives a purple to violet colour. In industry the same compound removes hair from hides in leather processing, a useful real-world link for chemistry and vocational lessons. Its solution is strongly alkaline, so wear gloves and eye protection when making it up.
What to Specify When Ordering
- The number of 100 g packs; modest stocks suit a solid that takes up moisture once opened.
- The tests you plan (metal sulfide precipitation, sulfide-ion test or hydrogen sulfide demonstration), so companion reagents can be added.
- Companion reagents such as lead acetate, sodium nitroprusside or dilute hydrochloric acid for the same enquiry.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies Sodium Sulfide from Ambala to schools, colleges and teaching or water-testing laboratories, with the MSDS sent alongside each 100 g pack.

How do you test for sulfide ions with Sodium Sulfide?
Dissolve a little Sodium Sulfide in water and add a few drops of freshly made sodium nitroprusside solution; a purple to violet colour confirms sulfide. Alternatively, warm a sample with dilute acid and hold moist lead acetate paper at the mouth of the tube, which turns black.
Why does Sodium Sulfide smell of rotten eggs?
Sodium Sulfide reacts slowly with moisture and carbon dioxide in the air, releasing traces of hydrogen sulfide with its rotten-egg smell. Keep the SCI-703/310 container tightly closed, open it in a ventilated area and never mix the solid with acids outside a fume cupboard.
How should Sodium Sulfide be stored?
Store Sodium Sulfide SCI-703/310 tightly closed in a cool, dry, ventilated cabinet, 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.

What Is Chromium Sulfate Used For?
Chromium(III) sulfate solutions are violet or green depending on what surrounds the chromium ion, and gently heating a violet solution turns it green as sulfate joins the complex — a simple way to introduce complex ions and ligand exchange. Adding sodium hydroxide gives a grey-green precipitate of chromium(III) hydroxide that dissolves in excess alkali to a green solution, the standard demonstration of an amphoteric hydroxide.
Warming that alkaline solution with hydrogen peroxide oxidises chromium(III) to yellow chromate, showing the change from the +3 to the +6 oxidation state; the product is a chromium(VI) compound and must be collected as hazardous waste. In industry, basic chromium sulfate is the tanning agent behind chrome-tanned leather, a useful applied-chemistry example. Wear gloves, avoid raising dust and keep all chromium residues out of the sink.
What to Specify When Ordering
- The number of 100 g packs each laboratory needs.
- The experiments you plan (complex-ion colours, amphoteric hydroxide test or oxidation to chromate), so companion reagents are included.
- Companion reagents such as sodium hydroxide and hydrogen peroxide for the same enquiry.
Supplier
ScienceLab is how Jain Scientific Equipments Private Limited trades, and the company supplies Chromium Sulfate from Ambala in 100 g packs with the MSDS for inorganic chemistry teaching. Colleges and schools often buy transition-metal salts as a set, so it can be quoted with nickel, cobalt, copper and iron salts for institutions, dealers and importers in India and international markets. Visit the ScienceLab profile for company details.
Related Laboratory Equipment

- Potassium Dichromate — the orange chromium(VI) salt for comparing oxidation states.
- Nickel Sulfate — a green nickel salt for side-by-side colour comparison.
- Hydrated Copper Sulfate — blue copper(II) sulfate for contrasting transition-metal colours.
See the full range of reagents in Laboratory Equipment.
Frequently Asked Questions
Why is Chromium Sulfate solution green or violet?
Chromium Sulfate solution is violet when only water molecules surround the chromium(III) ion and turns green when sulfate ions join the complex, which happens on heating. Chromium Sulfate SCI-705/311 lets students watch this ligand change, a clear introduction to complex ions.
How does Chromium Sulfate show amphoteric behaviour?
Add dilute sodium hydroxide to a Chromium Sulfate solution and a grey-green chromium(III) hydroxide precipitate forms; add more alkali and it dissolves to a green solution. Because the hydroxide also dissolves in acid, Chromium Sulfate SCI-705/311 is a standard amphoteric-hydroxide demonstration.
Is Chromium Sulfate hazardous?
Chromium Sulfate is a chromium(III) compound, less hazardous than chromium(VI) compounds such as dichromates, but it should still be handled with gloves and without raising dust. Follow the MSDS supplied with the 100 g SCI-705/311 pack and collect chromium residues for proper disposal.
How should Chromium Sulfate be stored?
Keep Chromium Sulfate SCI-705/311 in its closed container in a cool, dry place, away from strong 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.

What Is Hydrated Copper Sulfate Used For?
The classic practical is gently heating a few blue crystals in a dry china dish or test tube. The water of crystallisation is driven off and the solid turns white; adding a few drops of water turns it blue again and warms the container. Students see a reversible change and the chemical test for water in a single lesson.
A copper sulfate solution is also the usual starting point for displacement reactions, where zinc granules or an iron nail become coated with copper as the blue colour fades, and for electrolysis and copper-plating work with copper electrodes. Slow cooling of a warm saturated solution grows large blue crystals, the copper sulphate crystal activity many school science clubs enjoy. The salt is harmful if swallowed and toxic to aquatic life, so collect waste solutions instead of pouring them down the sink.
What to Specify When Ordering
- The number of 500 g packs needed for the term or academic year.
- Whether the order covers class practicals, crystal-growing projects or both, so quantities can be planned.
- Your delivery address, and whether the consignment ships within India or overseas.

Frequently Asked Questions
What is Hydrated Copper Sulfate 500 g used for?
Hydrated Copper Sulfate 500 g is used in school and college chemistry labs to show water of crystallisation, a reversible colour change, displacement of copper by more reactive metals, electrolysis and crystal growing. The 500 g analytical reagent pack suits departments running these practicals across several classes.
Why do Hydrated Copper Sulfate crystals turn white when heated?
Hydrated Copper Sulfate turns white on heating because the water of crystallisation responsible for the blue colour is driven off, leaving anhydrous copper sulfate. Adding water restores the blue colour and releases heat, which is why the white powder serves as a simple test for water.
What grade and pack size is this Hydrated Copper Sulfate?
This listing (SCI-709/313) is Hydrated Copper Sulfate of analytical reagent grade in a 500 g pack, supplied with its MSDS. If you need a different quantity, ask us about the separate Hydrated Copper Sulfate listing before you order.
How long does Hydrated Copper Sulfate 500 g keep in storage?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Hydrated Copper Sulfate 500 g. Ask us for the expiry date of the batch you are quoted, and keep the pack tightly closed in a cool, dry chemical cupboard.
Is Hydrated Copper Sulfate hazardous to handle?
Yes, Hydrated Copper Sulfate is harmful if swallowed, irritates the eyes and skin and is toxic to aquatic life. Students should wear goggles, avoid raising dust, wash hands after use and collect copper-containing waste for proper disposal, following the MSDS supplied with each pack.
Can schools order Hydrated Copper Sulfate 500 g in bulk or for export?
Yes. Schools, colleges and dealers can order Hydrated Copper Sulfate 500 g in multiple packs for delivery across India and international markets. Send the number of packs and the destination, and Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, will reply with a quotation.

Ferrous Sulfate (II) 100 g
Ferrous Sulfate (II) 100 g (Product Code: SCI-711/314) is an analytical reagent grade iron(II) sulfate used to demonstrate thermal decomposition, test for iron(II) ions and carry out the brown ring test for nitrates in secondary school and college chemistry laboratories. Teachers value the pale green crystals because one salt illustrates hydration, oxidation and decomposition, and each 100 g pack comes with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

What Is Ferrous Sulfate Used For?
In the thermal decomposition practical, a few crystals are heated in a hard-glass test tube: they first lose their water of crystallisation and colour, then break down into reddish-brown iron(III) oxide while sulfur dioxide and sulfur trioxide escape with a sharp smell. Use only a small quantity and carry it out in a fume cupboard or a well-ventilated room.
Freshly made solutions are used to identify iron(II) ions, since sodium hydroxide gives a dirty-green precipitate that browns on standing in air, and in the brown ring test for nitrate ions. Iron(II) solutions oxidise slowly in air, so prepare them just before the lesson and keep them covered. College students also meet the salt as a reducing agent that decolourises potassium permanganate in redox work.
What to Specify When Ordering
- How many 100 g packs your practical groups need.
- The hydration form you require, if your syllabus or method names one.
- Whether you also want the separate Ferrous Sulfate (II) listing or related iron salts on the same quotation.
- Your delivery location in India or abroad.

Frequently Asked Questions
What is Ferrous Sulfate (II) 100 g used for?
Ferrous Sulfate (II) 100 g is used for the thermal decomposition practical, for identifying iron(II) ions with sodium hydroxide, for the brown ring test for nitrates and as a reducing agent in redox experiments. It is an analytical reagent pack supplied with MSDS for school and college laboratories.
What happens when Ferrous Sulfate (II) crystals are heated?
Heated Ferrous Sulfate (II) crystals first lose their water of crystallisation and green colour, then decompose into reddish-brown iron(III) oxide while sulfur dioxide and sulfur trioxide are given off. Use a small amount in a hard-glass tube and work in a fume cupboard or well-ventilated room.
Why does a Ferrous Sulfate (II) solution turn yellow-brown?
A Ferrous Sulfate (II) solution turns yellow-brown because oxygen in the air slowly oxidises iron(II) ions to iron(III). Make the solution just before use, keep it covered and add a little dilute sulfuric acid to slow the change, particularly before the brown ring test.
Is Ferrous Sulfate (II) the same as iron(II) sulfate?
Yes. Ferrous Sulfate (II) is this catalogue's name for iron(II) sulfate; "ferrous" already means iron in the +2 state, so both names describe the same salt. Tell us if your method needs a particular hydrate so we can confirm the form in the 100 g pack.
What is the shelf life of Ferrous Sulfate (II)?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is given for Ferrous Sulfate (II) 100 g. Ask us for the expiry date of the batch you are quoted, and store the pack sealed in a dry cupboard to limit air oxidation.
How can a school or dealer order Ferrous Sulfate (II) 100 g?
Schools, colleges and dealers can order Ferrous Sulfate (II) 100 g by stating the number of packs, any required hydrate and the delivery address. Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, quotes for delivery across India and international markets.
