     · In the above process, after taking electrons the neutral copper atoms get deposited on the cathode. At the same time, SO 4 reacts with copper anode and becomes CuSO 4 but in water it can not exist as single molecules instead of that CuSO 4 will split into Cu + +, SO 4 − − and dissolve in water. So it can be concluded that, during electrolysis of copper sulfate with copper electrodes ...
