Nitric acid oxidizes the metal to +3 ions, but only in moment amounts, generally undetectable from the pure acid due to the chemical equilibrium of the reaction. Nevertheless, the ions are removed from the equilibrium by hydrochloric acid, forming AuCl−four ions, or chloroauric acid, therefore enabling more oxidation: For private https://kyleriptyd.wikibyby.com/796489/not_known_details_about_kaufe
