Question

In a Lead Storage battery [a] pbo2 is reduced to pbso4 at the cathode [b] pb is reduced to pbso4 at the anode [c] both electrodes are immersed in the same aqueous solution of H2so4b[d] all of the above

Answer 1

In a lead storage battery [d] all of the above statements are true.

Explanation:

• Lead storage battery is a rechargeable battery.
• In this battery, the energy is stored to use it later.
• This battery has pure lead as anode; lead(IV) oxide as cathode; and dilute sulfuric acid as electrolyte.
• When the battery is being used, lead(IV) oxide is reduced to PdSO₄ and lead is oxidized to PdSO₄.
• When the battery is being charged, PdSO₄ is again converted into PbO₂ and Pb as cathode and anode respectively.
