Question

When a lead storage battery is charge:

• A. $Pb{O}_2$ dissolves
• B. the lead electrode becomes coated with lead sulphate
• C. sulphuric acid is regenerated
• D. the amount of acid decreases

Answer 1

The correct option is C sulphuric acid is regenerated

Lead Storage Battery:-

$\to$ Lead Storage cell is a secondary voltaic cell.

$\to$ During the recharging process, original reactants are regenerated. Hence, electrical energy is stored.

$\to$ Electrolyte used in lead storage cell is $H_{2}S{O}_4$. During discharge $H_{2}S{O}_4$ is consumed., and during recharging concentration of $H_{2}S{O}_4$ increases as it is generated.
