CADMIUM CYANIDE Chemical Properties,Usage,Production

Chemical Properties

crystal(s) or white powder(s); turns brown if heated in air; used to electroplate cadmium [HAW93] [MER06]

Physical properties

White, cubic crystal or powder; density 2.226 g/cm³; sparingly soluble in water 1.71g/100mL (at 15°C); slightly soluble in alcohol; dissolves in alkali, metal cyanides, and hydroxides.

Uses

In copper bright electroplating.

Preparation

Cadmium cyanide may be prepared by treating a concentrated aqueous solution of cadmium chloride or cadmium nitrate with potassium cyanide or sodium cyanide. The white precipitate obtained is filtered, washed and dried.
CdCl₂ + 2KCN → Cd(CN)₂ + 2KCl.
