Potassium Ferrocyanide
Potassium Ferrocyanide (Product Code: SCL-931/208) is an analytical reagent, also known as potassium hexacyanoferrate(II), used to confirm metal ions such as iron(III), copper(II) and zinc in qualitative salt analysis in senior secondary, college and teaching laboratories. Chemistry teachers and lab assistants order it in 500 gm packs supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

What Is Potassium Ferrocyanide Used For?
In the practical syllabus, a freshly prepared aqueous solution of potassium ferrocyanide is added dropwise to the salt solution under test. A deep blue precipitate (Prussian blue) points to iron(III) ions, while a chocolate-brown precipitate is characteristic of copper(II); it is also used in the confirmatory test for zinc. Because the result depends on a clear colour change, students should work with clean test tubes, add the reagent slowly and compare against a known sample where possible. Teachers running salt analysis for a whole batch usually prepare one stock solution for the session and discard leftovers rather than storing them for long periods.
The solid should be kept tightly closed in a cool, dry place, away from strong acids: mixing ferrocyanides with strong acids, especially when heated, can release toxic gas, so tests should be done in a well-ventilated area and waste collected as directed in the MSDS. For schools and colleges that want a single chemistry consumables supplier in India for reagents and apparatus, this reagent can be quoted together with glassware, racks and safety items.

Frequently Asked Questions
What pack size is Potassium Ferrocyanide available in?
Potassium Ferrocyanide is listed in a 500 gm pack of analytical reagent grade. For larger requirements, tell us the total quantity your laboratories need and we will confirm how the order can be packed and quoted.
What does Potassium Ferrocyanide show in salt analysis?
Potassium ferrocyanide gives a deep Prussian blue precipitate with iron(III) ions and a chocolate-brown precipitate with copper(II), and it is also used in the confirmatory test for zinc, so one reagent covers several cations.
Does Potassium Ferrocyanide come with an MSDS?
Yes, Potassium Ferrocyanide is supplied with an MSDS. Keep the sheet with your chemical store records and follow its guidance on storage, spill handling and disposal of test waste containing the reagent.
What is the shelf life of Potassium Ferrocyanide?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is given for Potassium Ferrocyanide. Ask us for the expiry date of the batch you are quoted, and keep the container tightly closed and dry.
Is Potassium Ferrocyanide hazardous to store with acids?
Yes. Potassium ferrocyanide should be stored away from strong acids, because ferrocyanides mixed with them, especially when heated, can release toxic gas. Follow the MSDS for segregation in your chemical store.
Who supplies Potassium Ferrocyanide?
Potassium Ferrocyanide is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, in 500 gm analytical reagent packs with an MSDS, for senior secondary schools, colleges and teaching laboratories in India and international markets.
