Vedclass · Answer

(C) During the discharge of a lead storage battery,the following reactions occur:At anode: $Pb(s) + SO_4^{2-}(aq) \rightarrow PbSO_4(s) + 2e^-$At cathode: $PbO_2(s) + SO_4^{2-}(aq) + 4H^+(aq) + 2e^- \rightarrow PbSO_4(s) + 2H_2O(l)$$1$. $Pb$ is oxidized from $0$ to $+2$ at the anode.$2$. $PbO_2$ is reduced from $+4$ to $+2$ at the cathode.$3$. The equivalent mass of $H_2SO_4$ is its molar mass divided by its valency factor ($n$-factor). Since $H_2SO_4$ provides $2H^+$ ions,its $n$-factor is $2$. Thus,equivalent mass = $98 / 2 = 49$. Therefore,the statement that the equivalent mass is $98$ is incorrect.$4$. The extent of discharging depends on the concentration of $H_2SO_4$ as it is consumed during the reaction. Thus,the statement that it is independent is also incorrect. However,in standard multiple-choice contexts,the most fundamentally incorrect chemical property regarding the equivalent mass is often highlighted.
