Question

During the working of the lead acid battery, density of the solution

Answer 1

Answer:

The lead sulfate (PbSO

4

) is whitish in colour.

During discharging, both of the plates are covered with PbSO

4

.

The specific gravity of sulfuric acid solution falls due to formation of water during the reaction at PbO

2

plate.

As a result, the rate of reaction falls which implies the potential difference between the plates decreases during the discharging process.
