aqua regia is a solution of nitric acid+hydrochloric acid. ratio is 3:1.
Nitric Acid cannot react with Gold alone. The only solution that can dissolve Gold is Aqua Regia; a combination of Nitric Acid and Hydrochloric Acid.
Aqua regia: 3 parts hydrochloric acid and 1 part nitric acid; the acids are concentrated.Warning: this mixture is very corrosive and dangerous for the skin, eyes, etc. Careful working.
