1.	When lead storage battery is chargedA. Lead dioxide dissolvesB. Sulphuric acid is regeneratedC. The lead electrode becomes coated with lead sulphateD. The amount of sulphuric acid decreases
Answer» Correct Answer - 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.
