Just Boil the CuSO4 solution at 100°C temperature, so water molecules evaporated and solution become white coloured powder like substance that is dry dehydrated CuSO4.

Hi,hope this helps you...
First,we have to heat the CuSO4 solution to a saturated solution(about 3/4 of the water will be vaporised). Then leave the solution in a beaker to cool it. When the solution is let to cool down,crystallisation will occur. Normally,we leave it to form the crystals in 3 days. When you cool it,be sure to cover the solution so that no impurities will go inside. After that,filter the crystal out. Then,put it on a dry filter paper and let it dry. The salt formed is blue in colour which is not a copper sulphate salt. It is still hydrated (CuSO4.5H2O). To form the salt which is white in colour, you need to heat the hydrated CuSO4.5H2O salt strongly.
CuSO4.5H2O --> CuSO4 + 5H2O
