You guys are getting it all wrong. Sulphur (IV) oxide is not SO4^-2, it is SO3^2-. The most correct answer is C) it is an acid hydride.

sO2+H2O=H2sO3

The correct statement regarding sulfur dioxide (sulfur (IV) oxide) is:

D. It forms a white precipitate with acidified barium chloride.

When sulfur dioxide reacts with acidified barium chloride, it forms a white precipitate of barium sulfate. This reaction is often used as a test for the presence of sulfate ions in a solution.

The other options are incorrect:
A. Sulfur dioxide does not form tetraoxosulfate (VI) acid (H2SO4) with water. That is a property of sulfur trioxide.
B. Sulfur dioxide has a pungent odor.
C. Sulfur dioxide is not classified as an acid hydride. It is acidic in nature when dissolved in water, but it's not a classic example of an acid hydride.

ok yes I was wrong, it said H2SO4 with water as in products are H2SO4+H2O so the corr ans is c.

Options A and D describes the sulphate ion, SO4^2-, this is sulphur (VI) oxide. The sulphur (IV) oxide is also known as sulphite ion. Option B is incorrect because sulphur dioxide or Sulphur (IV) oxide has a pungent odour.

Everyone should be able to distinguish between these two gases with their oxidation numbers which influences their naming. Myschool, please verify the answer to this question

there is a difference between anhydride and hybride so the ans is A
