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

Options

A. `PbO_2`
B. `PbO`
C. `PbSO_4`
D. `Pb_3 O_4`

Answer

To solve the question about Compound A, we need to analyze the information provided step by step.

### Step 1: Identify the properties of Compound A
- The problem states that Compound A is a strong oxidizing agent, amphoteric in nature, and is part of lead storage batteries.

### Step 2: Understand what a strong oxidizing agent is
- A strong oxidizing agent is a substance that can accept electrons from other substances, causing those substances to be oxidized. In this case, we need to find a compound that fits this description.

### Step 3: Define amphoteric nature
- Amphoteric substances can react with both acids and bases. This means that Compound A must be able to undergo reactions in both acidic and basic environments.

### Step 4: List potential compounds related to lead storage batteries
- The compounds mentioned in the context of lead storage batteries are:
1. PbO2 (Lead dioxide)
2. PbSO4 (Lead sulfate)
3. Pb3O4 (Lead tetroxide)
4. PbO (Lead oxide)

### Step 5: Analyze the compounds
- **PbO2 (Lead dioxide)**:
- It is known to be a strong oxidizing agent and is used as the cathode in lead storage batteries.
- It can react with acids (forming PbSO4) and bases (forming lead hydroxide), indicating its amphoteric nature.

- **PbSO4 (Lead sulfate)**:
- This compound is not an oxidizing agent and does not exhibit amphoteric behavior.

- **Pb3O4 (Lead tetroxide)**:
- This compound does not fit the criteria of being a strong oxidizing agent.

- **PbO (Lead oxide)**:
- While it is amphoteric, it is not a strong oxidizing agent.

### Step 6: Conclusion
- Based on the analysis, the only compound that meets all the criteria (strong oxidizing agent, amphoteric, and part of lead storage batteries) is **PbO2 (Lead dioxide)**.

### Final Answer
- Compound A is **PbO2 (Lead dioxide)**.
