Principle of Electrolysis of Copper Sulfate Electrolyte

Feb 24, 2012Whenever 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.
