take some copper sulphate and put it in a test tube or a boiling tube.
heat the test tube
u will find that the blue colour of CuSO4 fades away
when u get a white powdery mass add water in a proper proportion that is 5 water molecules per molecule of CuSO4.
U GET BACK THE blue colour.
formula- CuSO4.5H2O.
the 4 an 2 mentioned should come below the compounds.
water of crystallisation is the no. of water molecules present per molecule of a compound.
Na2CO3.10H2O
FeSO4.7H2O
