What is meant by water of crystallisation?

Answer and explanation

Correct answer: A fixed amount of water in salt crystals

Water of crystallisation is the definite number of water molecules chemically associated with one formula unit of certain salt crystals. For example, copper sulphate crystals contain five water molecules, written as CuSO₄·5H₂O. It is not simply river water, any water mixed with acid, or a gas from a base. Thus, option A gives the correct definition.
