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.

When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
because the atomic structure is so dense it breaks through the dimensions and calls upon the gods for dissolving powers. then it takes an epic journey and becomes enlightened and melts through reality
"Soluble" is the word that describes sugar dissolving into water.
Dissolving
A solute that can be dissolved into a solvent to form a homogeneous mixture known as a solution. Common examples include salt dissolving in water or sugar dissolving in coffee.
Aqua regia is a popular name for an acid mixture capable of dissolving gold. It is a combination of concentrated nitric acid and hydrochloric acid.
Aqua regia, a mixture of nitric acid and hydrochloric acid, is capable of dissolving gold. The combination of these two acids creates a powerful solvent that can break down the gold's crystal lattice structure, allowing it to dissolve.
solvent: a liquid or a solid substance capable of dissolving other liquids or solids. solute: is the dissolved matter in a solution.
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
A solvent is a substance capable of dissolving other substances to form a solution. It is typically a liquid but can also be a solid or gas. Solvents are commonly used in various processes such as cleaning, chemical reactions, and extraction.
Silver is processed by dissolving it from gold alloys. This is done by boiling it within a 30 percent solution of nitric acid.
Dissolving takes place to turn a mechanical (heterogeneous) mixture into a solution (homogeneous solution).

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