  While charging the lead storage battery.......... (a) PbSO4 anode is reduced to Pb      (b) PbSO4 cathode is reduced to Pb (c) PbSO4 cathode is oxidised to Pb    (d) PbSO4 anode is oxidised to PbO2

Answer:

                  (a) While charging the lead storage battery the reaction occurring on cell is reversed and PbSO4 (s) on anode and cathode is converted into Pb and PbO2, respectively Hence, option (a) is the correct choice The electrode reactions are as follows At cathode At anode  (Oxidation) Overall reaction
