Write the overall reaction that occurs during use (discharging) of nickel-cadmium cell. Mention its one merit over the lead storage cell.

The acid used in lead storage cells is

During the recharging of lead acid storage cell the reaction at anode is

Which of the following reactions occurs at the anode during the recharging of lead storage battery ?

Which one of the following events occurs during the charging of a lead storage battery?

Cell reaction during discharging of lead storage battery at cathode is :-

Which of the following reactions occur at the cathode during the charging of a lead storage battery?

During discharge of a lead storage cell the density of sulphuric acid in the cell:

During the discharge of a lead storage battery, the density of sulphuric acid fell from 1.13 to 1.15 g/ ml^(−1) and sulphuric acid of the density of 1.3 g/ ml^(−1) is 40% by mass and that of the density of 1.15 g/ ml^(−1) is 20% by mass. The battery holds 3.5 litre of acid and the volume practically remained constant during the discharge. Calculate the no. of ampere hour for which the battery must have been used. The charging and discharging reactions are: Pb+SO_(4)^(-2)rarrPbSO_(4)+2e^(-) (charging) PbO_(2)+4H^(+)+SO_(4)^(2-)+2erarrPnSO_(4)+2H_(2)O (discharging)

Write the cell reaction of a lead storage battery when it is discharged. How does the density of the electrolyte change when the battery is discharged?
