\nGypsum is a mineral commonly found in evaporite deposits. Its chemical composition is calcium sulfate dihydrate, meaning it contains calcium sulfate (CaSO\u2084) and two molecules of water of crystallization per formula unit. The chemical formula for gypsum is CaSO\u2084\u00b72H\u2082O.
\n<\/section>\n
\nThe degree of hydration of calcium sulfate determines whether it is gypsum (dihydrate), plaster of Paris (hemihydrate), or anhydrite (anhydrous).
\n<\/section>\n
\nWhen gypsum (CaSO\u2084\u00b72H\u2082O) is heated, it loses water to form calcium sulfate hemihydrate (CaSO\u2084\u00b7\u00bdH\u2082O), which is commonly known as Plaster of Paris. Further heating removes all water, resulting in anhydrous calcium sulfate (CaSO\u2084), or anhydrite. Gypsum is widely used in plaster, drywall (gypsum board), cement production, and as a soil conditioner.
