Vedclass · Answer

(B) During the charging process,the lead storage battery acts as an electrolytic cell.At the anode (positive terminal during discharge,now connected to positive terminal of external source),$PbSO_{4}$ is oxidized to $PbO_{2}$:$PbSO_{4(s)} + 2H_{2}O_{(l)} \rightarrow PbO_{2(s)} + S{O_{4}}^{2-}_{(aq)} + 4H^{+}_{(aq)} + 2e^{-}$At the cathode (negative terminal during discharge,now connected to negative terminal of external source),$PbSO_{4}$ is reduced to $Pb$:$PbSO_{4(s)} + 2e^{-} \rightarrow Pb_{(s)} + S{O_{4}}^{2-}_{(aq)}$Therefore,$PbSO_{4}$ on the cathode is reduced to $Pb$.
