    (i) An aqueous solution of AgNO3?  with silver electrodes.
    At cathode: Silver ions have lower discharge potential than hydrogen ions. Hence, silver ions will be deposited in preference to hydrogen ions.

    At anode: Silver anode will dissolve to form silver ions in the solution.
    Ag → Ag+ + e−

    (ii) An aqueous solution of AgNO3?  with platinum electrodes.

    At cathode: Silver ions have lower discharge potential than hydrogen ions. Hence, silver ions will be deposited in preference to hydrogen ions.

    At anode: Hydroxide ions having lower discharge potential will be discharged in preference to nitrate ions. Hydroxide i
