Aqua Regia Site

: It is exceptionally corrosive and can cause severe chemical burns. Due to the risk of explosions and toxic fumes, laboratories often mandate a "buddy system" and the use of specialized Standard Operating Procedures in a fume hood. Major Industrial Uses

: It fumes vigorously and is extremely unstable. Because its active components decompose and escape as gas, it must be prepared immediately before use. aqua regia

Aqua Regia: The "Royal Water" That Dissolves Gold Aqua regia, which means in Latin, is a highly corrosive, fuming liquid. It earned its name from ancient alchemists because it is one of the few substances capable of dissolving "noble" metals like gold and platinum , which typically resist single-acid reactions. Composition and Chemical Reaction : It is exceptionally corrosive and can cause

While it is famous for its history in alchemy, modern industry uses aqua regia for several critical processes: Because its active components decompose and escape as

Aqua regia is not a single compound but a freshly prepared mixture of two strong concentrated acids: : 3 parts. Nitric Acid ( HNO3cap H cap N cap O sub 3 ) : 1 part.

) . These components work together in a two-step process: nitric acid acts as a powerful oxidant to produce tiny amounts of gold ions, while the hydrochloric acid provides chloride ions that react with those gold ions to form stable coordination complexes, effectively pulling the gold into the solution.
