Each oxygen (O) has an oxidation state of -2 (since oxygen is usually -2 in most compounds), and there are two oxygen atoms. To balance the total charge of the molecule, the sulfur must have an oxidation state of +4.<\/li>\n\n\n\n<li><strong>Incorrect<\/strong>: The statement that the oxidation state of sulfur in SO2 is +6 is wrong. It is actually +4.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>SO3 (Sulfur Trioxide)<\/strong>:\n<ul class=\"wp-block-list\">\n<li>In SO3, sulfur (S) has an oxidation state of <strong>+6<\/strong>. Each oxygen (O) atom is assigned an oxidation state of -2, and there are three oxygen atoms. To balance the overall charge, sulfur must have an oxidation state of +6.<\/li>\n\n\n\n<li><strong>Incorrect<\/strong>: The statement that the oxidation state of sulfur in SO3 is +4 is wrong. It is +6, not +4.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>H2SO4 (Sulfuric Acid)<\/strong>:\n<ul class=\"wp-block-list\">\n<li>In H2SO4, sulfur (S) also has an oxidation state of <strong>+6<\/strong>. The two hydrogen (H) atoms are each +1, and each oxygen (O) atom is -2. The four oxygen atoms contribute -8 in total. To balance the charges, sulfur must have an oxidation state of +6.<\/li>\n\n\n\n<li><strong>Incorrect<\/strong>: The statement that the oxidation state of sulfur in H2SO4 is +2 is wrong. It is +6, not +2.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The oxidation states of sulfur in SO2, SO3, and H2SO4 are +4, +6, and +6 respectively.
