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.

Aqua regia or aqua regis (Latin for king's water) is a highly corrosive, fuming yellow or red solution. The mixture is formed by freshly mixing concentrated nitric acid and concentrated hydrochloric acid, usually in a volumetric ratio of 1:3 respectively. It was so named because it can dissolve the so-called royal, or noble metals gold and platinum, although tantalum, iridium, osmium, titanium and a few other metals are able to withstand it.
Alkaline solutions of Potassium Cyanide. Mixture of concentrated hydrochloric and Nitric acids. Hot and concentrated Selenic acid.
Aqua regia or "king's water" it is a corrosive mixture of very concentrated hydrochloric acid and nitric acid.
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
A type of mixture that does not dissolve substances into one is called Immiscible.Miscible is when something is capable of blending or dissolving into another.

Dissolving
The Process Is called solution
solvent: a liquid or a solid substance capable of dissolving other liquids or solids. solute: is the dissolved matter in a solution.

Aqua regia:a mixture of concentrated HCL(hydrochloric acid)&conc. HNO3(nitric acid) in ratio of 3:1 ,can dissolve gold.
It is a solvent that dissolves in a solution.
Dissolving takes place to turn a mechanical (heterogeneous) mixture into a solution (homogeneous solution).
Silver is processed by dissolving it from gold alloys. This is done by boiling it within a 30 percent solution of nitric acid.

Solvent is the term for a dissolving medium in a solution. The material which is being dissolved is called the solute.
