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 hexafluorophosphate Silver hexafluorophosphate Silver hexafluorophosphate, sometimes referred to "silver PF-6," is an inorganic compound with the chemical formula AgPF. Silver hexafluorophosphate is a commonly encountered reagent in inorganic and organometallic chemistry. It is commonly used to replace halide ligands with the weakly coordinating hexafluorophosphate anion; the abstraction of the halide is driven by the precipitation of the appropriate silver halide. Illustrative is the preparation of acetonitrile complexes from a metal bromide, a reaction that would typically be conducted in a solution of acetonitrile: AgPF can act as an oxidant, forming silver metal as a by-product. For example, in solution in dichloromethane,
