Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfite with the formula CaSO 3 ·x(H 2 O). Two crystalline forms are known, the hemihydrate and the tetrydrate, respectively CaSO 3 ·½(H 2 O) and CaSO 3 ·4(H 2 O). All forms are white solids. It is most notable as the product of fluegas desulfurization.
