When `CuSO_(4)` is electrolysed, using Pt electrodesA. Copper is liberated at cathode, sulphur at anodeB. Copper is liberated at cathode, oxygen at anodeC. Sulphur is liberated at cathode, oxygen at anodeD. Oxygen is liberated at cathode, copper at anode. |

Answer» Correct Answer - B During electrolyses, copper is deposited at the cathode while oxygen is liberated at anode. The following reactions occur at the electrodes. At anode `2H_(2)O to 4H^(+) + O_(2) + 4e^(-)`(Oxidation) At cathode `Cu^(2+) + 2e^(-) to Cu(s)` (Reduction) |
