Silver cyanide reaction with other anions. Some silver cyanides are luminescent. Both AgCN and KAg(CN) have been used in silver-plating solutions since at least 1840 when the Elkington brothers patented their recipe for a silver-plating solution. A typical, traditional silver-plating solution would contain KAg(CN) 15-40 gL, KCN 12-120 gL and KCO gL. Silver cyanide Silver cyanide is the chemical compound with the formula AgCN. This white solid forms upon treatment of solutions containing Ag with cyanide. This precipitation step is used in some schemes to recover silver from solution. Silver cyanide is used in silver-plating. Its structure consist of -[Ag-CN]- chains in
Silver acetylide evolution of gaseous products and that its chemical formula is . In reality, it is a double salt with the silver salt it was produced from, usually silver nitrate. The anion of the parent compound acts as the oxidizer in the decomposition reaction. The detonation velocity of the mixture silver acetylide: silver nitrate is 3460 m/s. That of pure silver acetylide is 4000 m/s. Silver acetylide can be produced by passing acetylene gas through a solution of silver nitrate: The reaction product is a greyish to white precipitate. This is the same synthesis from Berthelot in which he first found
