Vedclass · Answer

(D) Roasting of sulphide ores involves heating them in the presence of excess air,which produces $SO_2$ gas as a byproduct.The chemical reaction is: $2MS + 3O_2 \rightarrow 2MO + 2SO_2$.$SO_2$ is a colourless gas with a choking smell of burnt sulphur.It causes damage to respiratory organs and is a major contributor to acid rain.Its aqueous solution is acidic $(H_2SO_3)$,it acts as a reducing agent,and the corresponding acid $(H_2SO_3)$ is unstable and has never been isolated in pure form.Therefore,the gas $X$ is $SO_2$.

Roasting of sulphides gives the gas $X$ as a byproduct. 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,acts as a reducing agent,and its acid has never been isolated.
The gas $X$ is
