To determine the oxidation state of the sulfur atom in H2SO4, we can use the oxidation state rules and the fact that the sum of the oxidation states of all atoms in a neutral molecule must be equal to zero.1. The oxidation state of hydrogen H is usually +1.2. The oxidation state of oxygen O is usually -2.In H2SO4, there are two hydrogen atoms, one sulfur atom, and four oxygen atoms. Let's assign the oxidation state of sulfur as x.Using the oxidation state rules and the fact that the sum of the oxidation states must be equal to zero, we can set up the following equation: 2 x +1 + 1 x x + 4 x -2 = 0Solving for x:2 + x - 8 = 0x - 6 = 0x = 6So, the oxidation state of the sulfur atom in H2SO4 is +6.
