What is the oxidation state of S in H₂SO4?<br> OA. +8<br> OB. +6<br> OC. -4<br> OD. -2
slega [8]

Answer:

B.) +6

Explanation:

To find the oxidation number of sulfur, we can assume the oxidation numbers of the other elements.

What I mean is, oxygen (O) always has an oxidation number of (-2). That being said, if there are 4 oxygen atoms, oxygen is contributing -8 overall. We also know that hydrogen generally has an oxidation number of (+1). Like before, if there are 2 hydrogens, it must be contributing +2.

If the overall molecule is neutral, we have to get these charges to balance out.

In essence, -8 + 2 + ? = 0?

If you combine the charges from oxygen and hydrogen, you are left with -6. Therefore, to make the molecule neutral, sulfur must have an oxidation number of +6.
