Roasting of sulphides gives the gas X as a by-product. This is a colourless gas with a choking smell of burnt sulphur and causes great damage to respiratory organs as a result of acid rain. Its aqueous solution is acidic and acts as an oxidizing agent and its acid has never been isolated. The gas X is:
1. SO2
2. CO2
3. SO3
4. H2S
