Simply if there is a change in the chemical composition of the reactants after the reaction(or action) we can say it's a chemical change. Else if you see physical state of a reactant change from one state to other it's a physical change.
In this case copper sulphate disassociates into copper and sulphate ions, so from a crystal to dissolved state( a physical change).
