Question

What would you observe, when the water of crystallization of a salt is removed by heating it?

Answer 1

When salts are heated strongly,they lose their water of crystallisation.By losing water of crystallisation,the hydrated salts lose their regular shape and colour,and become colourless powdery substances,

The salts which have lost their water of crystallisation are called anhydrous salts.

For Ex:Copper sulphate crystals are blue in colour.When copper sulphate crystals are heated strongly,they lose water of crystallisation and form anhydrous copper sulphate which is white in colour.
