Ferrous Sulfate (II)
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.

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.

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?
A Ferrous Sulfate (II) enquiry should state the code SCI-408/171, how many 200 g packs you need, the delivery location, and any related reagents such as potassium permanganate, so that one quotation covers the whole practical.
