• A salt is called as hydrated salt when it contains specific amount of water molecules present in its structure.

• The name and formula of three hydrate salts are as follows:

1. Calcium sulfate dihydrate:

• It has 2 water molecules attached with calcium sulfate.

• Thus its formula is CaSO4. 2H2O.

• It is commonly called as gypsum.

2. Calcium sulfate hemihydrate:

• It has half molecules of water attached to calcium sulfate.

• Thus its formula is CaSO4. 1/2 H2O.

• It is commonly called as plaster of Paris.
