Iron Sulfide
Iron Sulfide (Product Code: SCI-735/323) is an analytical reagent grade iron(II) sulfide used to generate hydrogen sulfide gas with dilute acid for qualitative analysis and gas-chemistry lessons in school and college laboratories. It comes as a 100 g pack with its MSDS and doubles as a reference sample of the compound formed when iron and sulfur are heated together. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry lab instruments supplier that also stocks reagents like this one.

What Is Iron Sulfide Used For?
Iron(II) sulfide reacts with dilute hydrochloric or sulfuric acid to release hydrogen sulfide, the gas traditionally used in qualitative salt analysis to precipitate metal sulfides from acidic and ammoniacal solutions. It is the usual charge for a Kipp's apparatus or a simple test-tube gas generator, and the gas is identified by the black stain it leaves on moist lead acetate paper.
Hydrogen sulfide is highly toxic, and its rotten-egg smell cannot be relied on because the gas quickly dulls the sense of smell, so generate only small amounts inside a fume cupboard and close the generator after use. Students can also compare this sample with the product of their own iron and sulfur heating experiment: with dilute acid the compound gives hydrogen sulfide, whereas the unheated mixture gives mostly hydrogen from the free iron.
What to Specify When Ordering
- The number of 100 g packs each laboratory needs.
- Whether this pack suits your gas generator, or whether the separately listed Ferrous Sulphide sticks fit your apparatus better.
- Companion reagents such as dilute hydrochloric acid and lead acetate for the same enquiry.
Supplier
Jain Scientific Equipments Private Limited, known by its trading name ScienceLab, supplies Iron Sulfide from Ambala in 100 g packs with the MSDS for analysis teaching in schools and colleges. It can be quoted together with acids, lead acetate and gas-handling glassware for institutions, dealers and importers in India and international markets. The ScienceLab company profile has further details.
Related Laboratory Equipment
Reagents and glassware used when generating and testing hydrogen sulfide:
- Hydrochloric Acid 2000 ml — diluted, it releases hydrogen sulfide from the sulfide.
- Lead Acetate — for the test paper that the gas turns black.
- Ferrous Sulphide sticks — the same compound in stick form under its own listing.
- Iron (Powder) — heated with sulfur so students can make iron sulfide themselves.
- Gas Washing Bottle — borosilicate bottle for bubbling the gas through a test solution.

Frequently Asked Questions
What is Iron Sulfide used for in the laboratory?
Iron Sulfide SCI-735/323 is used to generate hydrogen sulfide gas with dilute acid for precipitating metal sulfides in qualitative analysis, and as a reference sample of the compound formed from iron and sulfur. It comes as a 100 g analytical reagent pack with its MSDS.
How is hydrogen sulfide made from Iron Sulfide?
Add dilute hydrochloric or sulfuric acid to Iron Sulfide in a gas generator or test tube, working inside a fume cupboard. Hydrogen sulfide is released and can be bubbled into test solutions; confirm it with moist lead acetate paper, which turns black.
Is the gas from Iron Sulfide dangerous?
Yes. Hydrogen sulfide from Iron Sulfide is highly toxic, and its rotten-egg smell cannot be relied on because the gas quickly dulls the sense of smell. Generate only small amounts in a fume cupboard and follow the MSDS supplied with the SCI-735/323 pack.
How should Iron Sulfide be stored?
Keep Iron Sulfide SCI-735/323 in a tightly closed container in a dry place, away from acids, because moist air slowly attacks its surface. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
How does Iron Sulfide differ from Ferrous Sulphide sticks?
Iron Sulfide SCI-735/323 is a 100 g analytical reagent pack, while Ferrous Sulphide sticks are a separate listing of the same compound in stick form and a larger pack. Tell us which suits your gas generator, or ask us to quote both.
Who supplies Iron Sulfide SCI-735/323?
Iron Sulfide SCI-735/323 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, dealers and importers in India and international markets.
What does an Iron Sulfide quotation need?
An Iron Sulfide quotation needs the product code SCI-735/323, the number of 100 g packs, the delivery location and any acids or test papers you want on the same order. Send the details through the contact page or the enquiry cart.
