What is meant by "water of crystallisation" in a substance? Explain with an example.
(N/A) Water of crystallisation is the fixed number of water molecules present in one formula unit of a salt.
For example, hydrated copper sulphate is represented as $CuSO_{4} \cdot 5H_{2}O$.
In this formula, the $5H_{2}O$ signifies that there are five molecules of water present as water of crystallisation for every one formula unit of copper sulphate.
