Don't forget that sulfuric acid is a weak acid (especially with regard to its second proton), therefore Sodium Sulfite is mildly alkaline.

I believe you meant to say sulfurous acid and not sulfuric acid. Sodium sulfite is a salt of sulfurous acid (which IS a weak acid). Sulfuric acid is a strong acid and the corresponding sodium salt would be sodium sulfate.
