For lead storage battery pick the correct statements:

$\text{A. During charging of battery, PbSO}_4 \text{ on anode is converted into PbO}_2$

$\text{B. During charging of battery, PbSO}_4 \text{ on cathode is converted into PbO}_2$

$\text{C. Lead storage battery, consists of grid of lead packed with PbO}_2 \text{ as anode}$

$\text{D. Lead storage battery has } \sim 38\% \text{ solution of sulphuric acid as an electrolyte}$

Choose the correct answer from the options given below:

A
B, D only
B
B, C, D only
C
A, B, D only
D
B, C only

Answer

Correct answer:A

Step-by-step solution

Standard Method

Given: Statements about lead storage battery during charging and its construction are to be checked.

Find: Which statements among A, B, C, D are correct.

From the solution:

Statement A is false.
Statement B is true.
Statement C is false.
Statement D is true.

So the correct statements are B and D.

This matches option A.

Therefore, the correct option is A.

Common mistakes

Confusing the electrode materials of the lead storage battery is a common mistake. PbO $_2$ is associated with the positive plate, while Pb is the negative plate; do not interchange anode and cathode descriptions without checking the charging/discharging condition.
Assuming every statement about PbSO $_4$ converting to PbO $_2$ is true is incorrect. During charging, the two plates regenerate different active materials, so each statement must be checked separately.
