potassium ferrocyanide [pə′tas·ē·əm ‚fer·ō′sī·ə‚nīd]

(inorganic chemistry)

K₄Fe(CN)₆·3H₂O Yellow crystals with saline taste; soluble in water, insoluble in alcohol; loses water at 60°C; used in medicine, dry colors, explosives, and as an analytical reagent. Also known as yellow prussiate of potash.

Potassium Ferrocyanide

potassium hexacyanoferro-ate, K₄[Fe(CN)₆]⋅3H₂O, a complex iron (II) compound; light yellow crystals that remain stable in air. Density, 1.85 g/cm³.

Potassium ferrocyanide was first obtained by heating horns, hooves, and blood with K₂C0₃ and iron filings. It is used as a reagent for Fe³⁺ ions, with which it forms the blue precipitate Prussian blue, Fe ₄[[Fe(CN)₆].₃. Potassium ferrocyanide is also of use in other branches of analytical chemistry. In industry it is used in the manufacture of paints, K₃[Fe(CN)₆].
