Aqua regia - Wikipedia

Aqua regia dissolves gold, though neither constituent acid will do so alone, because, in combination, each acid performs a different task. 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 gol
