Answer:

What is the formula for so42?

SO₄²-

Explanation:

2 Answers. Sulfate ion has two valid structures that you could draw, one with sulfur having a formal charge of zero and one with sulfur having a formal charge of +2.

The oxidation number of the sulfur atom in the SO42- ion must be +6, for example, because the sum of the oxidation numbers of the atoms in this ion must equal -2.

To find its valency ,I can advice you 2 ways which I often use are: a. SO4 is an anion which has came from an acid H2SO4, in which hydrogen as always has valency 1. Since hydrogen is more electro+ve than SO4,its oxidation no. will be +1.
