For #55b on the homework the Lewis structure for the hydrogen sulfite ion (HSO3^-1) has the hydrogen in a single bond with an oxygen atom. Why can't the hydrogen have a single bond with the sulfur atom?

Because hydrogen sulfite is an oxoacid, the hydrogen bonds to the oxygen.

Hydrogen is more likely to bond to one of the oxygen atoms because oxygen is more electronegative than sulfur is.
