Ammonia and Hydrochloric Acid (White Smoke)

NH3 + HCl → NH4Cl

Ikhtisar

Ammonia gas reacts with hydrogen chloride gas to form white fumes of ammonium chloride solid. This dramatic reaction occurs when concentrated ammonia and hydrochloric acid bottles are placed near each other, as the vapors meet in air and create a white smoke cloud.
