Calcium Sulphate Formula

The chemical formula for calcium sulfate is CaSO4. It consists of one calcium ion (Ca2+) and one sulfate ion (SO42-), which are held together by ionic bonds. Calcium sulfate exists in different forms, including anhydrous (without water) and hydrated forms such as hemihydrate (CaSO4·1/2H2O) and dihydrate (CaSO4·2H2O). The hydrated forms have different physical and chemical properties compared to the anhydrous form, making them useful in various industrial applications such as in construction, food industry, and pharmaceuticals.
