Which of the following products are formed when a lead storage battery is discharged? Correct Answer PbSO4
During the working of the lead storage battery, PbSO4 is formed at both the electrodes and sulphuric acid is used up. At the anode, Pb is oxidised to form PbSO4 and at the cathode, PbO2 is reduced to form PbSO4.
