Gypsum - Chemical Formula, Properties, Types, Uses and FAQ

The main components of gypsum are calcium sulfate (CaSO 4) and water (H 2 O). Its chemical name is Calcium Sulphate Dihydrate and the chemical formula of gypsum is represented as CaSO 4.2H 2 O. Gypsum and Anhydrite (CaSO 4) are very similar chemically just that gypsum has 2 water molecules and Anhydrite does not contain any water molecules.
