potassium ferricyanide

[pə′tas·ē·əm ‚fer·ə′sī·ə‚nīd]
(inorganic chemistry)
K3Fe(CN)6 Poisonous, water-soluble, bright-red crystals; decomposes when heated; used in calico printing and wool dyeing. Also known as red potassium prussiate; red prussiate of potash.

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.
