White or gray, granular powder that darkens on exposure to light. Silver cyanide is used primarily for silver plating. Some chemical tarnish removal methods use dilute cyanide solutions for dipping followed by a water rinse. Cyanide solutions will react with silver to produce silver cyanide residues which are highly toxic.
