Aqua Regia (s.l.)

Keyword Definition

Strictly speaking, aqua regia is a mixture of 3 parts HCl to 1 part HNO₃. However, in common usage, it refers to any mixture of HCl and HNO₃. The mixture has a strong oxidizing power due to the formation of nascent chlorine and nitrosyl chloride.

HNO₃ + HCl → NOCl + 2H₂O + 2(Cl)

NOCl → NO + (Cl)
