What Is Aqua Regia? Aqua Regia Definition and Preparation Aqua regia is a highly corrosive mixture of hydrochloric acid (HCl) and nitric acid (HNO 3) in a molar ratio of 3:1 or 4:1 The name “aqua regia” translates from Latin to mean “king’s water” or “royal water,” referring to the acid’s ability to dissolve the noble metals gold, platinum, and palladium
