Medium of sodium extract is

Options

A. Netural
B. Basic
C. Acidic
D. Depends on organic compound

Answer

To determine the medium of sodium extract, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Sodium Fusion Test**:
- The sodium fusion test is a qualitative analysis method used to detect the presence of certain elements in a compound, specifically halogens, nitrogen, and sulfur.

2. **Process of Sodium Fusion**:
- In this test, the sample is fused with sodium metal. This process converts the organic sample into inorganic salts.

3. **Preparation of Sodium Extract**:
- After fusing the sample with sodium, the resulting mixture is treated to extract the sodium salts. This is known as the sodium extract.

4. **Boiling the Sodium Extract**:
- The sodium extract is then boiled with iron(II) sulfate (FeSO4). This step is crucial for the subsequent analysis.

5. **Acidification**:
- The next step involves acidifying the mixture with concentrated sulfuric acid (H2SO4). This acidification is essential to create the right conditions for the analysis.

6. **Determining the Medium**:
- Since the sodium extract is treated with concentrated sulfuric acid, the medium of the sodium extract is acidic.

7. **Conclusion**:
- Therefore, the medium of sodium extract is acidic.

### Final Answer:
The medium of sodium extract is **acidic**.
