Identify the overall charge of the polyatomic ion SO_4^{2-}, which is -2.
Recall that oxygen almost always has an oxidation state of -2 in compounds.
Since there are 4 oxygen atoms, calculate the total oxidation contribution from oxygen: 4 \(\times\) (-2) = -8.
Let the oxidation state of sulfur be x. Write the equation for the sum of oxidation states equal to the overall charge: x + (-8) = -2.
Solve for x: x = -2 + 8, which gives the oxidation state of sulfur.
