Asked by Alyssa

net ionic equation to show that sulfurous acid, H2SO3, behaves as an acid in water.

I got this answer but do not know if it is correct.
H2SO3 + H2O --- H3O + SO

I am Not sure if its is tri/mono/diprotic

Your equation isn't balanced and is incorrect.
Its diprotic because it has two H atoms that ionize.
molecular equations are
H2SO3 ==> H^+ + HSO3^- and
HSO3^- ==> H^+ + SO3^2-
but I think the question is asking just for the first one to show it gives H3O^+. The net ionic equation is
H2SO3 + H2O ==> H3O^+ + HSO4^-

Actually I just got this question wrong because that guy was wrong. The right answer is diprotic and the equation is H2SO3 + H2O ==> H3O^+ + HSO3^-
