Answer 1

Answer:

Aqua regia must be prepared and used in a fume hood. To prepare, combine three (3) parts of hydrochloric acid to one (1) part nitric acid in a glass container. The hydrochloric acid must be measured into the glassware first, and then the nitric acid is slowly added. Never exceed 38% nitric acid.

Aqua regia is a mixture of hydrochloric acid (HCl) and nitric acid (HNO3) at a ratio of either 3:1 or 4:1. 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.
