What type of a battery is lead storage battery? Write the anode and the cathode reactions and the overall reactions occuring in a lead storage battery when current is drawn from it.
Write the cell reactions which occur in lead storage battery when the batteyr is on charging.
How does the concentration of sulphuric acid change in lead storage battery when current is drawn from it?
Write the chemistry of recharging the lead storage battery, highlighting all the materials that are involved during recharging.
During the discharge of a lead storage battery, the density of sulphuric acid fell down from 1.294 to 1.139 g/ml. Sulphuric acid of density 1.294g/ml is 39% H_2SO_4 by weight and that of density of 1.139 g/ml is 20% H_2SO_4 by weight. The battery holds 3.5 L of acid and the volume remains practically constant during discharge. calculate the number of ampere hours for which the battery must have been used. The charging and discharging reactions are: Pb^(2+)+SO_4^(2-)LeftrightarrowPbSO_4+2bare(Charging) PbO_2+4H^(+)+SO_4^(2-)+2bareLeftrightarrowPbSO_4+2H2O(Discharging) .
When an electric cell is charged, then:
Write cell reactions which occur in lead storage battery When battery in use.
What is a secondary batteyr? Write the mechanism of recharging of lead storage battery with the help of chemical reaction.
