WAEC Chemistry 2021 Theory — Question 15

Model answer

The cell consists of a silver rod as the anode and the copper ornament as the cathode, both dipped in a solution of AgNO3 (silver trioxonitrate(V)) electrolyte, connected to a DC power source with the anode at positive terminal and cathode (copper ornament) at negative terminal. Silver dissolves at the anode and deposits onto the copper ornament at the cathode.
