Auric cyanide

The product usually contains about three molecules of water of crystallization. It may alternatively be prepared by adding caustic soda solution to sodium auric cyanide ... [Pg.328]

Auric cyanide, Au(CN)a.—Potassium auricyanide is transformed by strong acids such as hydrofluosilicic acid into auric cyanide. The reaction is more complex than is indicated by the equation... [Pg.349]

Aurous acetylide does not form when passing acetylene through an aqueous solution of auric chloride. Instead metallic gold precipitates. Precipitation does not occur when introducing acetylene into a solution of auric chloride alkalized by potassium hydroxide nor into aqueous or ammoniacal solutions of potassium auric cyanide [67]. Unwanted formation of aurous acetylide has been reported during preparation of some alkynylgold(I) complexes [68]. [Pg.321]

Aurous cyanide, AuCN.—The cyanide is produced by the interaction of hydrogen cyanide and auric hydroxide8 by double decomposition... [Pg.339]

Gold arsenides.—Arsenic precipitates from auric-chloride solution an arsenide, AugAs.6 Fusion of thus substance with potassium cyanide converts it into a yellow arsenide, Au4As3, of density 16-2. Both substances have the character of alloys. [Pg.349]
