Answer
Water of crystallisation — When a crystal is separated or deposited from a hot saturated solution on gentle cooling of the solution, it generally unites with a definite number of water molecules and enters into a loose chemical combination with them. This definite number of water molecules is called water of crystallisation.
The geometric shape and colour of the crystal is correlated with water of crystallization.
