Vedclass · Answer

(B) During the charging process of a lead storage battery,the chemical reactions are the reverse of the discharging process.At the anode,$PbSO_4$ is converted to $PbO_2$ by oxidation:$PbSO_4(s) + 2H_2O(l) 	o PbO_2(s) + SO_4^{2-}(aq) + 4H^{+}(aq) + 2e^-$At the cathode,$PbSO_4$ is reduced to $Pb$:$PbSO_4(s) + 2e^- 	o Pb(s) + SO_4^{2-}(aq)$Therefore,the reaction at the anode is $PbSO_4 + 2H_2O 	o PbO_2 + SO_4^{2-} + 4H^{+} + 2e^-$.

During the charging of a lead storage battery,the reaction at the anode is:
