Vedclass · Answer

(B) During the charging of a lead storage battery,the cell acts as an electrolytic cell. The chemical reactions are the reverse of the discharging process.At the cathode: $PbSO_{4} + 2H_{2}O \rightarrow PbO_{2} + SO_{4}^{2-} + 4H^{+} + 2e^{-}$At the anode: $PbSO_{4} + 2e^{-} \rightarrow Pb + SO_{4}^{2-}$Overall reaction: $2PbSO_{4} + 2H_{2}O \rightarrow Pb + PbO_{2} + 2H_{2}SO_{4}$As shown in the overall reaction,$H_{2}SO_{4}$ is produced (regenerated) during the charging process.
