Ferrocianur Potassium
Ferrocianur Potassium (Product Code: SCI-515/222) is potassium ferrocyanide, an analytical reagent grade complex salt used to identify iron(III), copper(II) and zinc ions by coloured precipitates during qualitative analysis in school and college laboratories. This 100 g pack comes with an MSDS, and the catalogue name is a non-English spelling of potassium ferrocyanide. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Potassium Ferrocyanide Used For?
Potassium ferrocyanide is best known for the Prussian blue test: added to a solution of an iron(III) salt such as ferric chloride, it forms a dark blue precipitate at once. Students use it for confirmatory tests in inorganic salt analysis, and a school chemistry lab equipment list in India normally pairs it with potassium ferricyanide so both oxidation states of iron can be checked.
The same reagent gives a chocolate-brown precipitate with copper(II) ions and a white precipitate with zinc ions, so one bottle confirms several cations. The yellow crystals dissolve readily in water; make up small volumes of fresh solution for each practical and label the bottle clearly. As with other cyanide complexes, keep it away from hot concentrated acids, which can liberate hydrogen cyanide, and dispose of residues as the MSDS directs.
Supplier
Jain Scientific Equipments Private Limited supplies Ferrocianur Potassium under its ScienceLab name from Ambala, Haryana, together with the iron and copper salts needed to demonstrate each test. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT). Further details are on the ScienceLab profile page.
Related Laboratory Equipment
Cation confirmatory tests with Ferrocianur Potassium usually draw on these items:
- Iron Chloride (III) (200 g) — an iron(III) salt that turns Prussian blue with this reagent.
- Hydrated Copper Sulfate 500 g — provides copper(II) ions for the brown precipitate test.
- Ferricianur Potassium — the matching reagent for detecting iron(II) ions.
- Bottle Dropping — dispenses the test solution a few drops at a time.
- Test Tube Holder — for handling tubes safely while warming or shaking them.
The Laboratory Equipment category lists further reagents for salt analysis.
Frequently Asked Questions
What is Ferrocianur Potassium?
Ferrocianur Potassium is the catalogue spelling of potassium ferrocyanide, K4[Fe(CN)6], also named potassium hexacyanoferrate(II). Listing SCI-515/222 is an analytical reagent grade laboratory chemical supplied in a 100 g pack together with its MSDS.
Which ions can Ferrocianur Potassium identify?
Ferrocianur Potassium identifies iron(III) ions by a dark Prussian blue precipitate, copper(II) ions by a chocolate-brown precipitate and zinc ions by a white precipitate. It is therefore used for confirmatory tests in the cation section of school and college salt analysis.
How is Ferrocianur Potassium different from Ferricianur Potassium?
Ferrocianur Potassium contains iron in the +2 state and detects iron(III) ions, whereas Ferricianur Potassium (potassium ferricyanide) contains iron in the +3 state and detects iron(II) ions. Laboratories that teach both oxidation states of iron usually keep the pair side by side.
What is the shelf life of Ferrocianur Potassium?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Ferrocianur Potassium. Ask us for the expiry date of the batch you are quoted, and store the pack sealed in a cool, dry cabinet away from acids.
Are vendor registration details available for Ferrocianur Potassium orders?
Yes. Ferrocianur Potassium is supplied by Jain Scientific Equipments Private Limited, whose CIN and GSTIN appear in the Supplier section above for tender and vendor forms. Send any further registration documents with your enquiry and we will advise what we can provide.
Can Ferrocianur Potassium be ordered in larger quantities?
Ferrocianur Potassium can be quoted in multiples of the 100 g pack for schools, colleges, dealers and laboratories in India and international markets. Share the number of packs and the delivery destination, and the quotation will come from Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.
