Gold hydroxide is a brown precious metal compound, which tend to decompose when heating. It is insoluble in water and dilute acid, however soluble in strong acid, strong alkali and sodium cyanide solution. Gold(III) hydroxide is amphoteric,which is not stable and tend to decompose to AuO(OH) when heating to 100℃, Au2O3 when heating to 140-150℃. Potassium chloroaurate or gold chloride is the raw material.
