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)
