What is meant by water of crystallisation?

Answer and explanation

Correct answer: Fixed amount of water in salt crystals

Water of crystallisation means the definite number of water molecules chemically associated with one formula unit of certain salts and incorporated into their crystal structure. For example, CuSO₄·5H₂O contains five water molecules per formula unit. This is not simply river water or any water mixed with an acid, and it is not a gas formed from a base. Therefore option A is correct.
