This mixture is called Aqua regia (Latin: royal water) or aqua regis, which is a highly corrosive, fuming yellow or red solution, also called nitro-hydrochloric acid.

The mixture is formed by freshly mixing concentrated nitric acid (12M) and concentrated hydrochloric acid (18M), usually in a molar ratio of 1:3 (volume ratio 1:2) respectively.

Only this mixture is capable of dissolving gold (Au).

Chemical reaction equation (Be aware of toxic fumes !):

Au(s) + NO3-(aq) + 4 H+(aq) → Au3+(aq) + NO(g) + 2 H2O(l)

What solution is capable of dissolving gold?

Aqua regia, which is a mixture of two acids, will dissolve gold. Aqua regia is a mixture of concentrated nitric acid (HNO3) and concentrated hydrochloric acid (HCl), usually in a 1 to 3 ratio respectively. Aqua regia is one of the few acids that will dissolve both gold and platinum as well as other metals. Interestingly, neither hydrochloric acid nor nitric acid alone will dissolve gold, but together, they will!Both acids do different jobs. Nitric acid actually dissolves a virtually undetectable amount of gold, which reacts with the hydrochloric acid to produce ions that are much more soluble. This frees the nitric acid to dissolve the gold further, and the reaction continues.See the Web Links to the left for more information about aqua regia.
