In H2SO4, the oxidation state of sulfur is +6. Here's the breakdown of the oxidation states for each element in the compound:- Hydrogen H has an oxidation state of +1.- Oxygen O has an oxidation state of -2.Since there are two hydrogen atoms and four oxygen atoms, the total oxidation states for hydrogen and oxygen are +2 and -8, respectively. To balance the overall charge of the compound, the oxidation state of sulfur S must be +6.
