Aqua regia is a mixture of nitric acid (HNO3) and hydrochloric acid (HCl), optimally in a molar ratio of 1:3.
It is a yellow-orange fuming liquid, so named by alchemists as it can dissolve* the noble metals gold and platinum, though not all metals.
*NOTE - This is a common confusion that the gold is lost.
No,it is not.
Remember that Gold is dissolved and not decomposed so we can get it back.
like salt from salt solution.
So gold isn't wasted away.
