Why is sulfite SO3 2?
Both Sulfur and oxygen are located at VIA group in the periodic table. So, oxygen and sulfur atoms have six electrons in their valence shell. There are -2 charge on SO32- ion. Therefore there are two more electrons which contribute to the valence electrons.

Sulfite | O3S-2 – PubChem.
What pH is H2SO3?
At low pH, the dominant form is HSO3 -, with a pKa (H2SO3) of 1.8, 12,51 whereas SO3 2-, with a pKa (HSO3 -) of 7.2, becomes the main form in a near-neutral pH environment. …
Why does SO3 2 have a double bond?
Adding two extra electrons changes that by giving two more electrons to sulfur. To keep standard valence rules, sulfur has either a double bond and two single bonds (hypervalent) or three single bonds and a formal positive charge (octet rule).
Is h2so3an acid or base?
Weak Acid: dissolves but less than 100% dissociates to produce protons (H+) 1. any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) 2. solutions of weak acids have a low concentration of H+.
Is HNO3 a weak acid?
If you see any other acid or base than one of these strong ones it will be a weak acid or base (unless I specifically say otherwise in the problem). The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). The weaker the weak acid the stronger it’s conj base.
