Answer #1

The answer to this question has been explained in two parts : Part 1 and Part 2

Part 1 explains the disproportionating nature of Pb (lead) i.e. it undergoes oxidation and reduction simultaneously.

Part 2 deals with the working of a lead storage battery cell and gives the reason as to why OPTION C is correct.Page No Date Port 1 al reduce 2PbSO GO4 H2 AH 315.9 kT this is a disproportionation H the sami dement Ps undng Aeduction LHS ces oocidation and RHS and oumuttancowly ridueu from 4 to t2 Nour, obteuing the options gimen a Pb02 vis hesiueed i may be the armer (C s option is piinal optim 30,w.haue、t-.
