  2. Answer:

    When sulphur dioxide is dissolved in water, then it forms sulphurous acid (H2SO3).

    Explanation:

    Metals react with oxygen to form metallic oxides. These metallic oxides are basic in nature because they react with water to form bases. On the other hand, non-metals react with oxygen to form non-metallic oxides and these oxides differ from metallic oxides because they are acidic in nature. Also, non-metallic oxides react with water to form acids. Sulphur is non-metal, and sulphur dioxide (SO2) is acidic in nature. Thus, it reacts with water to form sulphurous acid (H2SO3 or H2O.SO2)

    The chemical reaction is: SO2 + H2O → H2SO3
