Answer
Substances which contain water molecules along with salts like Sodium carbonate decahydrate [Washing soda crystals — Na2CO3.10H2O] and Copper (II) sulphate pentahydrate [Blue vitriol — CuSO4.5H2O] are hydrated substances. This water gives the crystals their shape. In some cases it also gives them their colour (copper sulphate crystals are blue in colour).
