What is meant by

Class 10th Lakhmir Singh & Manjit Kaur - Chemistry 2. Acids, Bases and Salts

Answer :

The salts which contain water of crystallisation are called hydrated salts. Example: Copper sulphate crystals contain 5 molecules of water of crystallisation. The salts which have lost their water of crystallisation are called anhydrous salts. Example: On strong heating, copper sulphate crystals lose all the water of crystallisation and form anhydrous copper sulphate which is white in colour.
