    Aqua regia dissolves gold, even 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 3+).

    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

    10/2/20110183;32;I prefer to do aqua regia reactions in closed condensed reactors and I mix up the acid at 51 because the effect of the condenser recycles some of the nitric. The best method is to use as little nitric as you possibly can. Since you must use up any free nitric before you can drop the gold out of solution any extra nitric requires extra steps.
