Ferrous Ammonium sulphate Manufacturer,Supplier and Exporter in India

Ferrous Ammonium sulphate (Product Code: SCL-847/167), widely known as Mohr’s salt, is a pale green iron(II) double salt used to prepare standard solutions for permanganate and dichromate titrations in chemistry laboratories. It resists air oxidation better than plain ferrous sulphate, which is why senior secondary schools and colleges weigh it out directly; each pack holds 500 gm of analytical reagent with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

What Is Ferrous Ammonium Sulphate (Mohr’s Salt) Used For?

The best-known practical is the determination of the strength of a potassium permanganate solution. Students weigh Mohr’s salt accurately on a chemical balance, dissolve it in water containing some dilute sulphuric acid, make it up to the mark in a volumetric flask, and titrate portions against permanganate from a burette. No separate indicator is needed: the first lasting pale pink colour marks the end point. This experiment, together with its oxalic acid counterpart, forms the core of the redox section of a typical titration kit for schools.

Dilute sulphuric acid is added when dissolving the salt to stop hydrolysis and slow oxidation of iron(II) by air, so make the solution on the day of use. The salt also features in crystallisation practicals, where students prepare Mohr’s salt from ferrous sulphate and ammonium sulphate. Keep the stock container closed and dry; crystals that have turned yellowish-brown on the surface have partly oxidised and are no longer suitable as a standard.

Frequently Asked Questions

Is Ferrous Ammonium sulphate the same as Mohr’s salt?
Yes. Ferrous Ammonium sulphate is the chemical name of Mohr’s salt, the pale green iron(II) ammonium double sulphate. Syllabi and practical manuals use both names for the same compound, so either name can be used in an enquiry.

Why is Ferrous Ammonium sulphate preferred over ferrous sulphate for standard solutions?
Ferrous Ammonium sulphate is more stable in air than ferrous sulphate, so its iron(II) content stays reliable enough to weigh out directly as a standard. Ferrous sulphate oxidises more readily, which makes its solutions less dependable for accurate titration work.

How much Ferrous Ammonium sulphate is in a pack, and what grade is it?
Each pack of Ferrous Ammonium sulphate (SCL-847/167) contains 500 gm of analytical reagent grade material, supplied with an MSDS. The pack serves the permanganate and dichromate titrations that make up the redox section of a practical course.

What is the shelf life of Ferrous Ammonium sulphate?
The shelf life of Ferrous Ammonium sulphate depends on the chemical, its grade and storage conditions, so no fixed expiry period is quoted. Ask us for the expiry date of the batch you are quoted, and store the crystals sealed and dry to limit surface oxidation.

Can I request a batch assay report for Ferrous Ammonium sulphate?
Ferrous Ammonium sulphate is listed as analytical reagent grade and supplied with an MSDS. If your laboratory needs a batch assay report or other documents, please contact us before ordering so we can confirm what is available.

Who supplies Ferrous Ammonium sulphate (SCL-847/167)?
Ferrous Ammonium sulphate (SCL-847/167) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company provides titration reagents and glassware to senior secondary schools and colleges in India and international markets.

What should an institutional order request for Ferrous Ammonium sulphate include?
An order request for Ferrous Ammonium sulphate should mention the product code SCL-847/167, the number of 500 gm packs, the delivery address and GST billing details, so that the quotation can be prepared promptly and accurately.
