    GALVANIC CELL
    Galvanic cell (also called voltaic cell) uses chemical reaction to produce electrical energy (flow of electrons).

    Electrons will not flow in the following apparatus:

    But if reaction carried out in the apparatus shown in this Fig . (Cu/Ag system), electrons are transferred from Zn° to Cu+2 through a wire producing electrical energy.
    The salt bridge is necessary to complete the circuit and maintain charge neutrality.
    Zn+2 cathode
    SO4-2 anode
