What will happen during the electrolysis of aqu eous solution of `CuSO_(4)` in the presence of Cu electrodes?A. Copper will deposit at cathodeB. Copper will disolve at anodeC. Oxygen will be released at anodeD. Copper will deposit at anode |

Answer» Electrolysis of `CuSO_(4)` can be represented by two half cell reactions these occuring at cathode and anode respectively as At cathode `Cu^(2+)+2e^(-)rarrCu(s)` At anode `Cu(s)rarrCu^(2+)+2e^(-)` Here, Cu will deposit at cathode while copper will dissolved at anode. Hence, options a and b are the correct choices. |
