When these two are combined, they react to form volatile products like and free chlorine ( Cl2cap C l sub 2

: 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 aqua regia

) . 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. Physical Properties and Safety When these two are combined, they react to

While it is famous for its history in alchemy, modern industry uses aqua regia for several critical processes: These components work together in a two-step process:

: 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 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.
