Does nitric acid dissolve gold?

Gold! The metal will not react with or dissolve in straight nitric acid, only in aqua regia (nitric acid hydrochloride - a concentrated mixture of HCl & HNO3 in a 3:1 ratio). In this mixture, the metal is converted into AuCl4- anions in two stages and the resulting solution turns yellow (as nitrogen dioxide is produced as part of the reaction):

Does mercury destroy gold?

As other answers have pointed out, you can't 'destroy' gold chemically. Putting it in a nuclear reactor for an extended period of time will functionally convert most of it to an isotope of mercury. This won't really get rid of it, but gold dissolves readily in mercury at room temperature to form an amalgam.

Does gold float in mercury?

Objects That Can Float On Mercury

Can you remove mercury from gold?

A. The mercury will migrate into the gold similar to a splash of water migrating into dry wood. You will need to autoclave (outside extraction!) the ring at a temperature above the boiling point of mercury and below the softening point of gold (to be safe I would recommend at least 3 days).
