Howdy, buddy!

       
AIM -  To determine the water of crystallization.
Materials we need - copper sulphate crystals, test tube holder, burner, boiling tube. 
Procedure - ★ heat few crystals of copper sulphate in a dry boiling tube.

 ★we will observe that on heating blue crystals of copper sulphate, it becomes colourless and few drops of water are seen on the test tube.

★ then, on adding few drops of water to the heated copper sulphate, the blue colour of copper sulphate reappears.

the water of crystallisation is the fixed number of water molecules present in one formula unit of salt.
