Potassium ferricyanide


Also found in: Encyclopedia, Wikipedia.
(Chem.) red prussiate of potash; a dark, red, crystalline salt, K6(CN)12Fe2, consisting of the double cyanide of potassium and ferric iron. From it is derived the ferrous ferricyanate, Turnbull's blue.

This reduction is readily observed by change in the absorption maximum of potassium ferricyanide [K3Fe(CN)6], since it is reduced to potassium ferrocyanide [K4Fe(CN)6] by the CME which is then converted into ferri ferrocyanide Fe4[Fe(CN)6]3 in the presence of FeCl3.
