    Aqua regia dissolves gold, although neither constituent acid will do so alone. Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold ions (Au ). The hydrochloric acid provides a ready supply of chloride ions (Cl ), which react with the gold ions to produce tetrachloroaurate(III) anions, also in solution. The reaction with hydrochloric acid is an equilibrium reaction that favors formation of chloroaurate anions (AuCl4 ). This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloro

    Aqua regia dissolves gold, although neither constituent acid will do so alone. Nitric acid is a powerful oxidizer, which will actually dissolve a virtually undetectable amount of gold, forming gold ions (Au ). The hydrochloric acid provides a ready supply of chloride ions (Cl ), which react with the gold ions to produce tetrachloroaurate(III) anions, also in solution. The reaction with hydrochloric acid is an equilibrium reaction that favors formation of chloroaurate anions (AuCl4 ). This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloroauric acid. In addition, gold may be dissolved by the chlorine present in aqua regia. Appropriate equations are: Au + 3 HNO 3 + 4 HCl [AuCl 4] + 3 [NO 2] + [H 3O] + 2 H 2O or Au + HNO 3 + 4 HCl [AuCl 4] + [NO] + [H 3O] + H 2O.Solid tetrachloroauric acid may be isolated by evaporating the excess aqua regia, and removing residual nitric acid by repeatedly heating with hydrochloric acid. That step reduces nitric acid (see decomposition of aqua regia). If elemental gold is desired, it may be selectively reduced with sulfur dioxide, hydrazine, oxalic acid, etc. The equation for the reduction of gold by sulfur dioxide is: 2 AuCl 4 (aq) + 3 SO 2(g) + 6 H 2O (l) → 2 Au (s) + 12 H (aq) + 3 SO 4(aq) + 8 Cl (aq).Similar equations can be written for platinum. As with gold, the oxidation reaction can be written with either nitric oxide or nitrogen dioxide as the nitrogen oxide product: Pt (s) + 4 NO 3 (aq) + 8 H (aq) → Pt (aq) + 4 NO2 (g) + 4 H2O (l)3Pt (s) + 4 NO 3 (aq) + 16 H (aq) → 3Pt (aq) + 4 NO (g) + 8 H2O (l).The oxidized platinum ion then reacts with chloride ions resulting in the chloroplatinate ion: Pt (aq) + 6 Cl (aq) → PtCl 6 (aq).
