VerwendenGold(III) chloride is used in colloidal gold solutions, in photography and as a print toning agent(gold toning), starting solution to form other gold compounds and a precursor for preparation of ultra pure gold metal. It is used in electroplating and electroless plating as an anode in an electric cell. Gold(III) chloride acts as a gold catalyst and cell body stains for bright field and dark field microscopy.
synthetischeGold(III) chloride may be produced by the combination of metallic gold with chlorine gas at elevated temperatures: 2Au + 3Cl2 → 2AuCl3 It may be prepared in the laboratory by the reaction of iodine monochloride with metallic gold: 2Au + 6ICl → 2AuCl3 + 3I2 The compound should be stored tightly closed and protected from light.

DefinitionA compound prepared by dissolving gold in aqua regia. The bright yellow crystals (chloroauric acid) produced on evaporation are heated to form dark red crystals of gold(III) chloride. The chloride decomposes easily (at 175°C) to give gold(I) chloride and chlorine; at higher temperatures it decomposes to give gold and chlorine. Gold(III) chloride is used in photography. It exists as a dimer, Au2Cl6.
