Which of the following oxides is amphoteric is nature ?

Options

A. `AI_(2)O_(3)As_(2)O_(3)ZnO`
B. `CO,NO,N_(2)O`
C. `SO_(3),SO_(2),Cl_(2)O_(7)`
D. `Na_(2)O,MgO,BaO`

Explanation

To determine which of the given oxides is amphoteric in nature, we need to understand the definition of amphoteric oxides and analyze the options provided.

### Step-by-Step Solution:

1. **Understanding Amphoteric Oxides**:
Amphoteric oxides are those that can react with both acids and bases. This means they can exhibit both acidic and basic properties depending on the reaction conditions.

2. **Identifying Common Amphoteric Oxides**:
Common examples of amphoteric oxides include:
- Aluminum oxide (Al₂O₃)
- Zinc oxide (ZnO)
- Beryllium oxide (BeO)

3. **Analyzing the Given Options**:
The options provided in the question are:
- Aluminum oxide (Al₂O₃)
- Arsenic oxide (As₂O₃)
- Zinc oxide (ZnO)

4. **Evaluating Each Oxide**:
- **Aluminum Oxide (Al₂O₃)**: This oxide is known to be amphoteric. It can react with acids (forming aluminum salts) and bases (forming aluminates).
- **Arsenic Oxide (As₂O₃)**: While arsenic oxides can exhibit some amphoteric behavior, they are primarily considered acidic. Thus, it is less commonly classified as amphoteric compared to aluminum and zinc oxides.
- **Zinc Oxide (ZnO)**: This oxide is also amphoteric. It can react with both acids (to form zinc salts) and bases (to form zincates).

5. **Conclusion**:
Based on the analysis, both aluminum oxide and zinc oxide are amphoteric. Arsenic oxide is more acidic in nature. Therefore, the amphoteric oxides among the options given are:
- Aluminum oxide (Al₂O₃)
- Zinc oxide (ZnO)

### Final Answer:
The amphoteric oxides from the given options are Aluminum oxide (Al₂O₃) and Zinc oxide (ZnO).
