When a lead storage battery is charged:...

When a lead storage battery is charged:

A

Lead dioxide dissolves

B

Sulphuric acid is regenerated

C

The lead electrode becomes coated with lead sulphate

D

The amount of sulphuric acid decreases

Text Solution

Verified by Experts

The correct Answer is:
B
During charging of a lead storage battery, the reaction at the andoe and cathode are
anode: `PbSO_(4)+2e^(-)toPb+SO_(4)^(2-)`
Cathode: `PbSO_(4)+2H_(2)OtoPbO_(2)+4H^(+)+SO_(4)^(2-)+2e^(-)`
In both the reactions `H_(2)SO_(4)` is regenerated.
