Compound A used as a strong oxidizing agent is amphoteric in nature. It is the part of lead storage batteries. Compound A is :
Show Hint
- \(\mathrm{PbO}\)
- \(\mathrm{PbO_2}\)
- \(\mathrm{PbSO_4}\)
- \(\mathrm{Pb_3O_4}\)
The Correct Option is B
Solution and Explanation
\(\mathrm{PbO_2}\) is a strong oxidising agent (Pb is in the +4 state and is reduced to +2) and is amphoteric: it reacts with acids and with strong bases (forming plumbates).
PbSO4 is the discharge product and is not an oxidiser; PbO is amphoteric but not a strong oxidiser and not a part of the cell; Pb3O4 is not used in the battery.
Answer: (2) PbO2

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
