Define water of crystallisation with two examples. How will you prove their existence in the examples given by you ? |
|
Answer» SOLUTION :The FIXED number of water molecules present in one FORMULA unit of a SALT is water of crystalisation. The water of crystalisation in the salt is responsible for the colour and the crystal structure of the SALTS. When a coloured salt crystal is subjected to heat, it loses both its colour and crystalline structure due to loss of water. This proves their existence in salts. |
