What happens when chloride, bromide and iodide are separately heated with conc. `H_(2)SO_(4)`?

Explanation

To answer the question about what happens when chloride, bromide, and iodide are separately heated with concentrated sulfuric acid (H₂SO₄), we can break down the reactions step by step:

### Step 1: Heating Chloride with Concentrated H₂SO₄
- When chloride ions (Cl⁻) are heated with concentrated sulfuric acid, hydrogen chloride gas (HCl) is produced.
- The reaction can be represented as:
\[ \text{Cl}^- + \text{H}_2\text{SO}_4 \rightarrow \text{HCl} + \text{HSO}_4^- \]
