A Secondary Battery: The Lead Storage Battery (cont.)
The construction and operation of a lead storage cell is summarized below
Click the buttons
below to activate the battery.
In
the battery above, which electrode is serving as the cathode during discharge?
| Left Electrode | Right Electrode |

Good!
Lead(IV) oxide is being reduced at the left
electrode, making it the cathode.
Remember,
reduction occurs at the cathode.
Given
the following standard reduction potentials, calculate the number of cells
needed in a 12 V lead storage battery; rearrange the half-reactions as
needed:
Work through the problem on a piece of paper. When finished, click on
each check to reveal answers for each step.
