Potassium Ferrocyanide Manufacturer,Supplier and Exporter in India
Product Code : EL-CL-12334
Jlab Export is a leading Potassium Ferrocyanide Manufacturer,and suppliers in India
Potassium Ferrocyanide (code EL-CL-12334) is potassium hexacyanoferrate(II), K4[Fe(CN)6], a salt whose complex anion precipitates iron(III) and copper(II) ions in two quite different colours. Students use it in salt analysis to confirm Fe3+ in the iron group and Cu2+ in the copper group. JLab makes this reagent in Ambala, India.

Prussian Blue and the Copper Brown Test
Added to a solution of iron(III) ions, the reagent gives a deep blue precipitate of Prussian blue, Fe4[Fe(CN)6]3. In analysis this follows dissolving the iron group hydroxide precipitate in dilute hydrochloric acid. With copper(II) ions in a solution acidified with ethanoic acid, it gives a chocolate-brown precipitate of copper(II) hexacyanoferrate(II), Cu2[Fe(CN)6], the confirmatory test for Cu2+.
