What is the oxidation state of each element in so32â?
Ierofanga [76]
 <span>Same answer, different setup. We know that the sum of the oxidation numbers is zero for a compound and the ionic charge for a polyatomic ion, and we know that sulfite ion is -2. 

Create an algebraic equation by multiplying the subscripts times the oxidation number of a single element.

+x -2 
S O3 

Solve for x 
x = +4</span>
