The beautiful shapes and colours
The beautiful shapes and colours of some crystals are formed due to the water of crystallization. These crystals require water to maintain their crystalline properties. So let's see what happens when you remove the water of crystallization from crystals by heating it. Take some copper sulphate in a test tube and heat it. you see that it loses water and turns into a white powdery substance termed anhydrous copper sulphate. When we add water to this powder it immediately regains it blue colour and crystalline shape. As a result of this property, chemicals like copper sulphate are known as hydrous substances or hydrates.
** Warning: Be careful in handling copper sulphate as it is irritating to the eyes and skin, and also can be harmful if swallowed. **
