Nitric acid oxidizes the metal to +3 ions, but only in minute quantities, generally undetectable within the pure acid due to chemical equilibrium on the response. Nevertheless, the ions are faraway from the equilibrium by hydrochloric acid, forming AuCl−four ions, or chloroauric acid, thereby enabling even further oxidation: The gold https://deanafjmp.wikienlightenment.com/7029958/not_known_facts_about_gold
