Is there any difference btw the uses of $C a S O_{4} .2 H_{2} O$ & $C a S O_{4} . \frac{1}{2} H_{2} O$ ?

Solution

Gypsum is a crystalline mineral of hydrated calcium sulphate (chemical formula $(C a S O_{4} . 2 H_{2} O) .$ Gypsum is colorless or white, is not highly water-soluble and is not at all hard. A mixture of gypsum and water can be poured; the gypsum hardens as the water evaporates.
In art gypsum is mainly used in the partly dehydrated form of plaster of Paris $(2 C a S O_{4} . H_{2} O)$ to make casts of objects or works of art in sculpture (moulds). The process entails making a negative form, of a sculpture, for istance, which is then coated with plaster of Paris.
