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?
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. Before moving to the next page, you should know the difference between a secondary and a primary battery. You should also understand the operation of a lead storage battery. |
