what happens when we electrolyse copper sulphate solution with carbon electrodes at positive electrode and at negative electrode? |
|
Answer» 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. |
