Anion water in gypsum (CaSO4·2H2O) and hemihydrate (CaSO4·1/2H2O)
On heating, dehydration of calcium sulphate dihydrate (CaSO 4 ·2H 2 O) takes place in steps, first forming CaSO 4 ·1/2H 2 O and finally anhydrous CaSO 4. Anion water is held tenaciously up to 350 °C. Application of heat causes successive loss of 3/2 water molecules linked to the Ca atom, and finally the anion water. References [1]
