What is aqua regia?

The only substance in the world capable of dissolving gold!

Aqua regia is a powerful mixture of hydrochloric and nitric acids whose name means "royal water" in Latin. It gets its name from it being strong enough to dissolve the "king of metals" - gold.

Fun fact: in Russian, "aqua regia" translates to "Tsar vodka!"
