Question

What is reaction between hydrochloric acid and nitric acid?¿

Answer 1

• Aqua Regia (HNO3 + 3HCl) is used to etch gold or platinum.
• It is a mixture of Nitric acid and Hydrochloric acid that is freshly mixed before use. Optimally it is in a molar ratio of 1 part nitric acid to 3 parts hydrochloric acid.

Answer 2

Answer:

Upon mixing of concentrated hydrochloric acid and concentrated nitric acid, chemical reactions occur. These reactions result in the volatile products nitrosyl chloride and chlorine gas: HNO3 + 3 HCl → NOCl + Cl2 + 2 H2O. as evidenced by the fuming nature and characteristic yellow color of aqua regia.
