Your dashboard and recommendations. 47045 views SO 4 2-: (+6) + 4(-2) = -2. The oxidation number of oxygen is - usually - 2, so the formula of sulfur(VI) oxide is: SO3 The Oxidation states in SO3 (g) are: Sulfur (+6) & Oxygen (-2), because SO3 (g) has no charge. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+. What is the oxidation state of each of the elements in this compound? Sulfur trioxide. Furthermore, the oxidation state of sulfur in sulfur dioxide is +4 while in sulfur trioxide it is +6. Expert Answer Answer (g) :- Fe2 (SO3)3 species contain SO3 (2-) ion. If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. Oxygen has an ON of 2- except when in the form of peroxide or superoxide.
