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 rates at which molecules come out of solution the solution is in?
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
Why does aqua regia dissolve gold and platinum?
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

What is a popular name for acid mixture capable of dissloving gold?
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.
What mixture of acids is capable of dissolving gold?
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.
What are meanings of solvent and solute?

How can you define solvent?
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.
How do you process silver?
Silver is processed by dissolving it from gold alloys. This is done by boiling it within a 30 percent solution of nitric acid.
Why does dissolving take place?
Dissolving takes place to turn a mechanical (heterogeneous) mixture into a solution (homogeneous solution).
Which term describes a substance that can be dissolved in a solution?
