Consider the following reaction : Cu (s) + 2Ag^+ (aq) to2Ag (s) + Cu^(2+) (aq) (i) Depict the galvanic cell in which the given reaction takes palce. (ii) Give the direction of flow of current (iii) Write the half-cell reactions taking place at the cathode and anode. |

Answer» SOLUTION :(i) The cell may be depicted as under `Cu(s) | Cu^(2+) (aq) || AG^(+) (aq) | Ag(s)` (II)Current will flow from silver to copper electrode in the external circuit. (III) At CATHODE: `2Ag^(+) (aq) + 2e^(-) to 2Ag (s)` At anode: `Cu(s) to Cu^(2+) (aq) + 2e^(-)` |
