EXPLAIN THE 3 MECHANISMS BY WHICH ELECTROCHEMICAL CELLS TRANSPORT THE CHARGE, EXPLAIN EACH OF THEM 1. Electrons carry charge between the electrodes and the outer conductor. 2. Anions and cations are the charge carriers between the cell. 3. The ionic conduction of the solution is linked to the electronic conduction at the electrodes by the reduction reaction at the cathode and the oxidation reaction at the anode.
