The nature of `B_2 O_3` is

Options

A. Neutral
B. Amphoteric
C. Acidic
D. Basic

Answer

To determine the nature of \( B_2O_3 \) (Boron Trioxide), we can follow these steps:

### Step 1: Identify the Composition of \( B_2O_3 \)
- \( B_2O_3 \) is composed of boron (B) and oxygen (O). Boron is a non-metal and oxygen is also a non-metal.

### Step 2: Classify the Oxide
- Non-metal oxides are generally classified as acidic oxides. Since boron is a non-metal, its oxide \( B_2O_3 \) can be expected to exhibit acidic properties.

### Step 3: Reaction with a Base
- To confirm the acidic nature, we can observe its reaction with a base. For example, when \( B_2O_3 \) reacts with sodium hydroxide (NaOH), it forms sodium metaborate (\( NaBO_2 \)) and water (\( H_2O \)):
\[ B_2O_3 + 2 NaOH \rightarrow 2 NaBO_2 + H_2O \]
- This reaction indicates that \( B_2O_3 \) behaves as an acid (reacting with a base).

### Step 4: Conclusion
- Based on its composition and behavior in reactions, we conclude that \( B_2O_3 \) is acidic in nature.

### Final Answer
The nature of \( B_2O_3 \) is **acidic**.
