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

Quizplus · Accepted Answer

The cell reaction for a lead storage battery has a standard potential of +1.92 V. To provide a potential of about 12 V, six cells need to be connected in series. Each cell contributes 2 V to the overall potential, thus six cells in series can provide a total potential of 12 V. Adjusting the pH to 12 or 1 would significantly affect the equilibrium of the reaction, and increasing the surface area of the electrodes would not change the potential of the reaction. Therefore, connecting six cells in series is the best choice to provide a potential of about 12 V.
