Predict the products of electrolysis in each of the following
(i) an aqueous solution of `AgNO_(3)` with silver electrodes.
(ii). An aqueous solution of `AgNO_(3)` with platinum electrodes.
(iii). A dilute solution of `H_(2)SO_(4)` with platinum electrodes.
(iv). An aqueous solution of `CuCl_(2)` with platinum electrodes.

Explanation

Cu is deposited on cathode and `O_(2)` is evolved at anode, `Cu^(2+)` ion conc. decreases progressively and solution becomes acidic due to the formation of HCI.
