Calcium Hydroxide and Sulfuric Acid

Ca(OH)2 + H2SO4 → CaSO4 + 2H2O

Genel Bakış

Calcium hydroxide reacts with sulfuric acid to form calcium sulfate and water. The product calcium sulfate is a sparingly soluble salt that partially precipitates. This reaction produces gypsum (calcium sulfate dihydrate), one of the most important construction materials.
