When lead storage battery is charged

Answer»

Lead dioxide dissolves
SULPHURIC acid is REGENERATED
The lead electrode becomes coated with lead sulphate
The amount of sulphuric acid decreases

Solution :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.
