Ammonia and Hydrochloric Acid

NH3 + HCl → NH4Cl

نظرة عامة

Ammonia gas reacts with hydrogen chloride gas to form white fumes of ammonium chloride. In aqueous solution, ammonia acts as a Brønsted base by accepting a proton from HCl. This reaction produces dense white smoke when concentrated solutions are brought near each other, one of chemistry's most dramatic demonstrations.
