It is stablest gold oxides, which is insoluble in water, however soluble in hydrochloric acid, concentrated nitric acid and sodium cyanide solution. Gold(III) oxide is sensitive to light and decompose gradually, so the container is brown bottle under low temperature. Gold hydroxide is the raw material.
