When lead storage battery discharged, then

During the charging of a lead-acid cell 

While charging the lead storage battery ______.

State the energy conversions in a dry cell.

Write electrode reactions and overall cell reaction when lead accumulator behaves as an electrolytic cell.

Write electrode reactions and overall cell reaction during the operation of lead storage cell.

Sketch lead storage cell.

Explain the charging process of lead storage battery with chemical reactions.

Write the chemistry of recharging the lead storage battery, highlighting all the materials that are involved during recharging.

A lead storage battery consists of a lead anode and a grid of lead packed with lead dioxide as the cathode. The electrolyte taken is 39% $H_{2}S{O}_4$ by mass having a density of $1.29gm{L}^{-1}.$ The battery holds 3.5 L of the acid. During the discharge of the battery, the density$H_{2}S{O}_4$ falls from$1.294gm{L}^{-1}$ to $1.139gm{L}^{-1}$ which is 20%$H_{2}S{O}_4$ by mass.

Moles of sulphuric acid lost during discharge is:
