The sulfite ion has a charge of -2. This is because there are three oxygen atoms with an oxidation number of -2 each, totaling -6, and the overall charge of the ion is -2. Thus, we can set up the equation:

-6 + 3x = -2

where x is the oxidation number of sulfur. Solving for x, we get:

x = +4

Therefore, the oxidation number of sulfur in the sulfite ion is +4.
