Crystals of copper sulphate contain water of crystallization

Crystals of copper sulphate contain water of crystallization
The water of crystallization gives certain crystals their gorgeous patterns and hues. Water is required for these crystals to preserve their crystalline characteristics. So, let's examine what occurs when you heat crystals to eliminate the water of crystallization. Heat some copper sulphate in a test tube. You can watch how it loses water and transforms into an anhydrous copper sulphate, a white powdery material. When anhydrous copper sulphate is exposed to air, it quickly returns to its original blue colour and crystalline structure. Chemicals like copper sulphate are classified as hydrous compounds or hydrates as a result of this feature.
