Answer #1

Pb(s) + HSO4- (aq) ------> PbSO4(s) + 2e- + H+(aq) (oxidation)

PbO2(s) + 2e- + 3H+(aq) + 1HSO4- (aq)) ---->   PbSO4(s) + 2H2O(l) (reduction)

over all reaction :

Pb(s) + HSO4- (aq) ------> PbSO4(s) + 2e- + H+(aq)

PbO2(s) + 2e- + 3H+(aq) + 1HSO4- (aq)) ---->   PbSO4(s) + 2H2O(l)

-----------------------------------------------------------------------------------------------------------

Pb (s) + PbO2 (s) + 2H+ (aq) + 2HSO4- (aq)   -----> PbSO4 (s) + H2O

------------------------------------------------------------------------------------------------------------------
