Composition of less Familiar Metal Cyanogen Complexes : Part I. Composition of Cu(i) and Cr(ii) Cobalticyanide by Electrometric Methods

Crystalline potassium cyanocobaltate(III) was prepared by Pichler's method and cuprous chloride by Groger's method. The composition of the precipitate formed by their interaction was determined employing potentiometric and amperometric techniques. Chromous chloride was prepared by Balltis and Bailor's method and its interaction with potassium cobalticyanide was similarly studied.
