Dissolving 'blue' copper sulphate in water is certainly a chemical change. copper sulphate is ionic in nature. When it is dropped in water the CuSo4 dissociates into positively charged copper ions and negatively charged sulphate ions. Thus, the polarity of water leads the positively charged ions to get attracted to the oxygen atoms with a partial negative charge and the negative atoms to get attracted to the hydrogen from water with partial positive charge. Therefore, it is a chemical change.
