${\bold{\underline{\underline{Procedure\::}}}}$

• Take few crystals of copper sulphate in a dry test tube.
• Heat it for a few minutes.
• The salt (crystals) turns white in colour

${\bold{\underline{\underline{Observation \: :}}}}$

• We notice water droplets on sides of the test tube.
• This shows that crystals of salts are not really dry.
• Add 2 - 3 drops of water on the sample of copper sulphate obtained after heating.

${\bold{\underline{\underline{Results \: :}}}}$

• The blue colour of copper sulphate is restored.
