    Compounds. The characteristic oxidation states of gold are +1 (aurous compounds) and +3 (auric compounds). The state +1 is generally quite unstable, and most of the chemistry of gold involves the state +3. Gold is more easily displaced from solution by reduction than any other metal. Even platinum will reduce Au 3 + ions to metallic gold.
