Hydrochloric Acid and Calcium Hydroxide

2HCl + Ca(OH)2 → CaCl2 + 2H2O

Übersicht

Hydrochloric acid reacts with calcium hydroxide (slaked lime) to form calcium chloride and water. Calcium hydroxide is a dibasic compound that requires two equivalents of HCl. This neutralization is widely used in water treatment and industrial acid waste handling.
