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 chloride This reaction is used in photography and film. Silver chloride Silver chloride is a chemical compound with the chemical formula AgCl. This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl and Pb). Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by greyish or purplish coloration to some samples. AgCl occurs naturally as a mineral chlorargyrite. Silver chloride is easily synthesized by combining aqueous solutions of silver nitrate and sodium chloride. It can also be produced by reacting silver nitrate with cobalt(II)
