The oxidation state of the sulfur atom in sulfuric acid H2SO4 can be determined by assigning oxidation numbers to each atom in the compound and then solving for the unknown oxidation state of sulfur.1. Hydrogen has an oxidation state of +1.2. Oxygen has an oxidation state of -2.Now, we can set up an equation using the oxidation numbers and the chemical formula H2SO4:2 +1 + S + 4 -2 = 0Solving for S the oxidation state of sulfur :2 - 8 + S = 0S = +6So, the oxidation state of the sulfur atom in sulfuric acid H2SO4 is +6.
