Calcium Hydroxide and Sulfuric Acid

Ca(OH)2 + H2SO4 → CaSO4 + 2H2O

अवलोकन

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.

रोजमर्रा का उदाहरण

Gypsum board (drywall) used in virtually every modern building is made from calcium sulfate, which can be produced by this type of reaction.

औद्योगिक महत्व

Calcium sulfate (gypsum) is used in drywall, plaster, cement retarder, and as a food additive. Flue gas desulfurization uses lime to react with SO2, producing gypsum as a byproduct.
