Give the four steps in the process of crystallisation done in order to separate copper(II) sulfate from water.

1) The solution is heated to evaporate some of the water to make the solution more concentrated. 2)Eventually the solution becomes saturated, if you cool it now crystals will stat to form. 3) Leave the solution to cool. Crystals start to form in it as the temperature falls. 4) Remove the crystals by filtering, then rinse them with distilled water and dry them with filter paper.
