Aqua Regia Definition in Chemistry

Aqua regia is a mixture of hydrochloric acid (HCl) and nitric acid (HNO 3) at a ratio of either 31 or 41.It is a reddish-orange or yellowish-orange fuming liquid. The term is a Latin phrase, meaning "king's water". The name reflects the ability of aqua regia to dissolve the noble metals gold, platinum, and palladium. Note aqua regia will not dissolve all noble metals.
