Which single acid can dissolve gold?
“regal water” or “king’s water”) is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange (sometimes red) fuming liquid, so named by alchemists because it can dissolve the noble metals, gold and platinum, though not all metals.
What does sulfuric acid do to gold?

Can Stomach acid dissolve diamond?
