Compound A used as a strong oxidizing agent is amphoteric in nature.
Question:

Compound $\mathrm{A}$ used as a strong oxidizing agent is amphoteric in nature. It is the part of lead storage batteries. Compound $\mathrm{A}$ is :

1. $\mathrm{Pb}_{3} \mathrm{O}_{4}$

2.  $\mathrm{PbO}_{2}$

3. $\mathrm{PbSO}_{4}$

4.  $\mathrm{PbO}$

Correct Option: , 2

Solution:

lead storage batteries $\mathrm{PbO}_{2}$ is used. In this $\mathrm{O} . \mathrm{S}$. of $\mathrm{Pb}$ is $+4$ so it is always reduced and behaves as oxidizing agent
