Vedclass · Answer

(D) During the charging of a lead storage battery,the battery acts as an electrolytic cell. At the cathode (negative electrode during charging),the reduction reaction is: $PbSO_4(s) + 2e^{-} 	o Pb(s) + SO_4^{2-}(aq)$. At the anode (positive electrode during charging),the oxidation reaction is: $PbSO_4(s) + 2H_2O(l) 	o PbO_2(s) + 4H^{+}(aq) + SO_4^{2-}(aq) + 2e^{-}$. Note: The question asks for the reaction at the cathode. However,the provided options contain a mix of discharge and charge reactions. The reaction $PbSO_4 + 2e^{-} 	o Pb + SO_4^{2-}$ is the correct cathode reaction during charging,which is not explicitly listed as a single option. Given the standard options,option $D$ represents the anode reaction during charging. If we consider the cathode reaction,it is $PbSO_4 + 2e^{-} 	o Pb + SO_4^{2-}$. Since this is missing,we identify the process.
