What is the correct meaning of water of crystallisation?

Answer and explanation

Correct answer: A fixed amount of water present in salt crystals

Water of crystallisation is the definite number of water molecules chemically incorporated into the crystal structure of some salts. For example, washing soda is Na₂CO₃·10H₂O and copper sulphate crystals are CuSO₄·5H₂O. It is not ordinary river water, arbitrary water in an acid, or a gas, so option A is correct.
