Question

In a lead storage battery
1. PbO2 is reduced to PbSo4 at the cathode
2.Pb is oxidised to PbSo4 at anode
3. Both electrodes are immersed in same aqua solution of H2So4
4. All of the above are true

Answer 1

Answer:

4 .all of the above are true

Answer 2

For a lead storage battery, all the given statements are true.

• A lead storage battery is a chargeable device used to store energy which can be used later.
• A lead storage battery consists of an anode of pure lead and a cathode of lead(IV) oxide dipped in a dilute aqueous solution of sulfuric acid.
• When the battery is in use, the PbO2 at cathode is reduced while the Pb at anode is oxidized to PbSO4.
• When the battery is being charged, the PbSO4 is transformed back to PbO2 and Pb respectively.
