`Pb(s)+PbO_(2)(s)+2H_(2)SO_(4)(aq)to2PbSO_(4)(s)+2H_(2)O(l)`

BaCl_(2(aq))+H_(2)SO_(4(aq))toBaSO_(4(s))+2HCl_((aq)) is

In the reaction PbO_(2)+SO_(2) to PbSO_(4)

The concentration of H_(2)SO_(4) is used up. "Cell reaction : "PbO_(2)(s)+2H_(2)SO_(4)(aq)rarr PbSO_(4)(s)+2H_(2)O(l)

In the equation below, which species acts the oxidation agent? Pb(s)+PbO_(2)(s)+H^(+)(aq)+2HSO_(4)^(-)(aq)rarr2PbSO_(4)(s)+2H_(2)O(l)

A lead storage cell is discharged which causes the H_(2)SO_(4) electrolyte to change from a concentration of 34.6% by weight (density 1.261gml^(-1) at 25^(@)C ) to one of 27% by weight. The original volume of electrolyte is one litre. Calculate the total charge released at anode of the battery. Note that the water is produced by the cell reaction as H_(2)SO_(4) is used up. over all reaction is. Pb(s)+PbO_(2)(s)+2H_(2)SO_(4)(l)to2PbSO_(4)(s)+2H_(2)O(l)
