Which of the following is an amphoteric oxide

Options

A. MgO
B. `Al_(2)O_(3)`
C. `Cl_(2)O_(7)`
D. `Ti_(2)O_(2)`

Explanation

To determine which of the given options is an amphoteric oxide, we need to understand the properties of amphoteric oxides and analyze the options provided.

### Step-by-Step Solution:

1. **Define Amphoteric Oxides**:
Amphoteric oxides are those that can react with both acids and bases. This means they can act either as an acid or a base depending on the nature of the reacting substance.

2. **Identify Common Amphoteric Oxides**:
Some common examples of amphoteric oxides include:
- Aluminum oxide (Al₂O₃)
- Zinc oxide (ZnO)
- Lead(II) oxide (PbO)

3. **Examine the Options**:
If the options provided include Al₂O₃, ZnO, PbO, or similar compounds, we can identify them as amphoteric. In the video transcript, Al₂O₃ is specifically mentioned as an amphoteric oxide.

4. **Analyze Other Oxides**:
- **Al₂O₇**: This is likely referring to Al₂O₇, which is an acidic oxide. Acidic oxides typically react with bases but not with acids.

5. **Conclusion**:
Based on the analysis, Al₂O₃ is confirmed to be an amphoteric oxide.

### Final Answer:
The amphoteric oxide among the options is **Al₂O₃** (Aluminum oxide).
