Question

what is meant by water of crystallization

Answer 1

 Crystallization is a natural or artificial method of forming / making concrete crystals. Crystallation is used for molten or melt, or sometimes (very less) crystal deposits directly from the gas. Crystalline is a chemical concrete-liquid solubility technique in which the solvent transfers from liquid solution to pure solid. Crystallizer is used for crystalline in chemical engineering.

Answer 2

When a (for example )when the heat is provided to the copper sulphate crystals a small amount of water molecules settles on the tube and the colour of the copper sulphate becomes white so when this water is added to any solution the colour becomes different from the earlier one
so the water of crystalizition I s used to change the colour of any solution
