Why does only the organic layer assure colour and not the aqueous layer when the tests for halides are done?

Explanation

### Step-by-Step Solution:

1. **Understanding Halides**:
- Halides are anions such as chloride (Cl⁻), bromide (Br⁻), and iodide (I⁻). When testing for halides, we are typically looking to identify these ions.

2. **Oxidation to Diatomic Compounds**:
- In qualitative analysis, halides are oxidized to their diatomic forms:
- Chloride (Cl⁻) is oxidized to chlorine (Cl₂),
