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 chromate Silver chromate Silver chromate (AgCrO) is a brown-red monoclinic crystal and is a chemical precursor to modern photography. It can be formed by combining silver nitrate (AgNO) and potassium chromate (KCrO) or sodium chromate (NaCrO). This reaction has been important in neuroscience, as it is used in the "Golgi method" of staining neurons for microscopy: the silver chromate produced precipitates inside neurons and makes their morphology visible. Silver chromate is produced by an exchange reaction with a soluble silver salt, such as that between potassium chromate and silver nitrate. The use of the compound itself in the laboratory is rather
