Interpretation:
In lead acid battery, which substance is to be reduced, which substance is to be oxidized and which substance is to be produced in each reaction needs to be determined.
Concept introduction:
A lead storage battery is a type of rechargeable battery. These batteries have moderate power density and good response time. These batteries are affected by temperature.
Answer to Problem 45A
Lead dioxide is reduced
Lead electrode is oxidized
Explanation of Solution
In lead acid battery, the negative terminal composed of
Reaction at cathode
Lead electrode is oxidized to supply electron.
