Preparation


Gold(I) chloride is prepared by thermal decomposition of gold(III) chloride.



Reactions


Although there is a region of stability at higher temperatures at the appropriate chlorine vapor pressures, the compound is metastable at ambient conditions. When heated with water, the compound disporpotionates to metallic gold and gold(III) chloride in an autoredox reaction:


3 AuCl → 2 Au + AuCl3

Reaction with potassium bromide yields potassium auric bromide and potassium chloride with separation of metallic gold:


3 AuCl + 4 KBr → KAuBr4 + 2 Au + 3 KCl


Safety


Gold(I) chloride may irritate the skin and eyes, damage kidney function, and reduce white blood cell counts.
