Question

During the electrolysis of copper sulphate solution using copper electrodes is there any change in the mass of anode?​

Answer 1

hi friend,

here is your answer

Answer:

The change involves two electrons per copper ion.When copper electrodes are used in the electrolysis of copper sulfate solution, the mass loss of copper from the positive anode electrode should equal the mass of copper gained and deposited on the negative cathode electrode.

The anode (positive electrode ) is made from impure copper and the cathode (negative electrode) is made from pure copper. During electrolysis, the anode loses mass as copper dissolves, and the cathode gains mass as copper is deposited. A half-equation shows what happens at one of the electrodes during electrolysis.
