Question 1

For a particular battery based on one of the following reactions, E is expected to remain constant with time until the cell reactants are almost completely consumed. Which is the appropriate reaction?
◦ Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s)
◦ 2 NiO(OH)(s) + Cd(s) + 2 H2O(l) → 2 Ni(OH)2(s) + Cd(OH)2(s)
◦ Pb(s) + PbO2(s) + 2 H+(aq) + 2 HSO4-(aq) → 2 PbSO4(s) + 2 H2O(l)
◦ Zn(s) + 2 MnO2(s) + 2 NH4+(aq) → 2 NH3(aq) + Mn2O3(s) + Zn2+(aq) + H2O(l)

Question 2

The cell reaction for a lead storage battery is:

Pb(s) + PbO2(s) + 2 H+(aq) + 2 HSO4-(aq) → 2 PbSO4(s) + 2 H2O(l)
E° = +1.92 V

To provide a potential of about 12 V, one could
◦ adjust the pH to 1.
◦ connect six cells in series.
◦ greatly increase the surface area of the Pb(s) and PbO2(s).
◦ adjust the pH to 12.
