Which is the stronger acid, H2SO3 or HS-?
Which acid has the weaker conjugate base?
Which acid produces more ions?

H2SO3+H20=H30+HS03

HS+H20=H30+S^2-

I have no idea how to figure out these questions :(

Well, can you identify the acid and conjugate base and vice versa?
You can also look up the pK$_a$ of  each of the acids.

Yeah, I can identify those pretty well. Is the weaker acids conjugate base automatically the weaker conjugate base?

Oh wait, I just found this awesome table. So HSO3 is a much stronger acid, and if the acid is weak it means that the conj base is strong. Right?
