Gas X is SO2 (Sulfur Dioxide)

Properties of Gas X:
- Colorless gas with choking smell of burnt sulfur
- Causes damage to respiratory organs due to acid rain
- Aqueous solution is acidic
- Acts as a reducing agent
- Its acid has never been isolated

Explanation:

Roasting of Sulphides:
- When sulphides are heated strongly in the presence of oxygen, they undergo oxidation to form their respective oxides.
- This process is known as roasting.
- For example, the roasting of iron sulfide (FeS) produces iron oxide (Fe2O3) and sulfur dioxide gas (SO2).

Properties of Gas X:
1. Colorless gas with choking smell of burnt sulfur:
- Sulfur dioxide is a colorless gas with a pungent smell similar to the smell of burnt sulfur or a struck match.

2. Causes damage to respiratory organs due to acid rain:
- When sulfur dioxide is released into the atmosphere, it can react with water vapor to form sulfuric acid (H2SO4), which contributes to acid rain.
- Acid rain can cause damage to respiratory organs, aquatic life, and vegetation.

3. Aqueous solution is acidic:
- Sulfur dioxide dissolves in water to form sulfurous acid (H2SO3), which is a weak acid.
- The presence of sulfurous acid makes the solution acidic.

4. Acts as a reducing agent:
- Sulfur dioxide can act as a reducing agent, meaning it can donate electrons to other substances.
- In various chemical reactions, SO2 can undergo oxidation itself while reducing other species.

5. Its acid has never been isolated:
- Although sulfur dioxide can form sulfurous acid in aqueous solution, pure sulfurous acid has never been isolated as a stable compound.
- Sulfurous acid is unstable and readily decomposes into sulfur dioxide and water.

Therefore, based on the given properties, the gas X is sulfur dioxide (SO2).
