암모니아와 염산 (흰 연기)
NH3 + HCl → NH4Cl
개요
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.
