Potassium Ferricyanide

 

potassium hexacyanoferriate, K3[Fe(CN)6], a complex iron (III) compound; dark red crystals. Density, 1.86 g/cm3.

Potassium ferricyanide is obtained by the oxidation of potassium ferrocyanide. With Fe2+ ions it forms a dark blue precipitate of TurnbulFs blue, Fe3 [Fe(CN)6]2, which is of use inanalytical chemistry. Potassium ferricyanide is also used as areducer in photography.

The reaction to produce the Prussian blue or blueprint dye can also be carried out using other combinations of Fe II and Fe III salts, such as ferrous ammonium sulfate and potassium hexacyanoferrate (III) (Rodgers 2002).
