    Roasting of sulphides gives the gas X as a byproduct. This is a colorless gas with choking smell of burnt sulphur and causes great damage to respiratory organs as it results in acid rain. Its aqueous solution is acidic and acts as a reducing agent, and its acid has never been isolated. The gas X is

    A) \[S{{O}_{2}}\]

    B) \[C{{O}_{2}}\]

    C) \[S{{O}_{3}}\]

    D)  \[{{H}_{2}}S\]  

    Correct Answer: A

    Solution :

    \[S{{O}_{2}}\]gas is obtained when any sulphide are is roasted. \[2{{M}_{2}}S+3{{O}_{2}}\xrightarrow{{}}3{{M}_{2}}O+2S{{O}_{2}}\] This gas \[(S{{O}_{2}})\] exhibits all the characteristics as given in the question.
