     · Whenever copper sulfate or CuSO 4 is added to water it gets dissolved in the water. As CuSO 4 is an electrolyte it splits into Cu (cation) and SO 4 − − (anion) ions and move freely in the solution.. Now we will immerse two copper electrodes in that solution. The Cu ions (cation) will be attracted towards cathode i.e. the electrode connected to the negative terminal of the battery.
