# What are the products of the following reaction? SO_2 (g) + H_2O (l) ->

${H}_{2} S {O}_{3} \left(a q\right)$
Sulfur dioxide is the acid anhydride of $\text{sulfurous acid}$. Most inorganic chemists would prefer to view this as hydrated sulfur dioxide, i.e. $S {O}_{2} \cdot {H}_{2} O$ rather than ${H}_{2} S {O}_{3}$ but this is a very minor quibble. Are the formulae the same?
What do we normally call the hydrate of $S {O}_{3} \left(g\right)$?
