WebJun 5, 2024 · HNO3 + 3HCl (aqua regia) = NOCl + Cl2 + 2H2O Hot sulfuric acid and nitrate salt react to form nitric acid. The nitric acid reacts with hydrochloric acid to produce yellow nitrosyl chloride (NOCl) and chlorine (as it happens in aqua Regia). NOCl can also be broken down into NO and Cl2. 2NO + Cl2 equals 2NO + Cl2.
