The problem with gold is that it’s one of the least reactive chemical elements on the planet, which makes it difficult to dissolve. … “We use one of the most mass-produced chemicals, acetic acid, at five per cent concentration; it’s plain table vinegar,” explains Foley.

Why is aqua regia called royal water?

Aqua regia, mixture of concentrated nitric and hydrochloric acids, usually one part of the former to three parts of the latter by volume. This mixture was given its name (literally, “royal water”) by the alchemists because of its ability to dissolve gold and other so-called noble metals.
