Question

What do you mean by water of crystallization of a substance. Describe an activity to show that blue copper sulfate crystals contain water of crystallization

Answer 1

water of crystallisation is the fixed number of water molecules present in one formula unit of salt
experiment:
heat a few crystals of copper sulphate in a dry boiling tube. There will be a change in the colour
we can observe water molecules in the test tube
add 2-3 drops of water on the sample of copper sulphate obtained after heating
we will observe blue copper sulphate contain water of crystallisation
