#H_2SO_3(aq)#

Explanation:

Sulfur dioxide is the acid anhydride of #"sulfurous acid"#. Most inorganic chemists would prefer to view this as hydrated sulfur dioxide, i.e. #SO_2*H_2O# rather than #H_2SO_3# but this is a very minor quibble. Are the formulae the same?

What do we normally call the hydrate of #SO_3(g)#?
