Nitric acid oxidizes the steel to +three ions, but only in moment quantities, ordinarily undetectable while in the pure acid because of the chemical equilibrium from the reaction. Nonetheless, the ions are faraway from the equilibrium by hydrochloric acid, forming AuCl−four ions, or chloroauric acid, thereby enabling further oxidation: Also, https://sergiorwcg96395.blgwiki.com/793545/zahngold_verkaufen_tipps_und_informationen_zum_zahngoldankauf
