Aqua Regia is a mixture of concentrated HNO 3 and concentrated HCl. The Ratio for these acids is 1:3 by volume. Another name of Aqua Regia is royal water. It can be used to dissolve gold Au and platinum Pt in jewellery. It can dissolve all metals except silver (Ag). Reaction for the formation of Aqua Regia:
aqua regia (äk´wə rē´jēə) [Lat.,=royal water], corrosive, fuming yellow liquid prepared by mixing one volume of concentrated nitric acid with three to four volumes of concentrated hydrochloric acid. It was so named by the alchemists because it dissolves gold and platinum, the "royal" metals, which do not dissolve in nitric or hydrochloric acid alone.
The alchemists named this mixture "royal water" because of its ability to dissolve gold. It's a reddish-brown liquid. It's highly corrosive and might cause skin irritation. Gold and platinum are regularly dissolved with the use of Aqua Regia. Aqua Regia is a mixture of nitric acid and hydrochloric acid, at a molar ratio of 1: 3 optimally.

Aqua regia is a fuming red-yellow liquid at standard conditions, with a strong irritant smell. It is capable of reacting with gold, platinum and palladium, forming chloroauric acid, chloroplatinic acid and palladium (II) chloride respectively. Because of this ability, aqua regia is used in the gold and platinum refining processes.
