Question

What is meant by water of crystallization? How would you show
that copper sulphate contains water of crystallization?

Answer 1

Hey mate!

Here's your answer!!

#WATER OF CRYSTALLIZATION

❂Water of crystallisation is the number of water molecules that combine chemically in definite molecular proportion, with the concerned salt in the crystalline state.

❂This water is responsible for the geometric shape and colour of the crystals.

#EXPERIMENT

For example: the CuSO4.5H2O

❂Copper sulphate crystals are blue in colour. However, when copper sulphate is heated in a china dish for some time, the blue colour disappears and it becomes white-gray in colour. This is the anhydrous copper sulphate. The reaction is written as follows:

CuSO4•5H2O ➡ CuSo4 + 5H20

❂Thus the blue colour of copper sulphate crystals is due to water of crystallisation, which are lost when it is heated. Hence the blue colour of solution disappears. This proves that copper sulphate contains water of crystallisation.
