But, sulfur atom cannot be reduced furthermore because -2 is the lowest oxidation state of sulfur. Sufur can be 6-, 4-, 2-, 2+, 4+, or 6+, with 2- and 2+ being the most common. Therefore, the oxidation number of sulfur is +4 (it lost four electrons to oxygen) and the oxidation numbers for our compound is as follows: Na +1; S +4; O -2. Find the amount mass of 49 mass% NaSO4 solution to be added to 172 g of water to get 2 mass% solution of this salt. . Sulfur (in British English: sulphur) is a chemical element with the symbol S and atomic number 16. Chemistry Electrochemistry Oxidation Numbers. the sodium, Na+, ion and the disulfide, [S2O5]2-, ion, from the disulfide ion, the overall charge is -2. and we know that by rule, the ON for Oxygen is always -2. therefore the toal oxidation number for Oxygen is -2 x 5 = -10, this means that the total oxidation number for sulfur + -10 = -2, ie the total oxidation number of sulfur = 8 since 8 + -10 = -2, since there are two sulfurs, each sulfur will have and oxidation number of 4 (since 8/2 = 4). Chemistry. So that sulfur atom can be oxidized to sulfur's other higher oxidation states such as 0, +2 and +6. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. N2+ 3H2→2NH3How many grams of hydrogen, H2, are necessary to react completely with 50.0g of nitrogen, N2. So, three of the sulfurs have an oxidation number of 2+, one has an oxidation number of 4+, and the oxygens have 2-. the molecular formula of tertrathionate is s4o6^-2 the total charge on the atom is -2 so all the element s oxidation number should add upto a total of -2,let the oxidation number of sulphur be x, there are four sulphurs so 4x,generally the oxidation number of oxygen is -2(-1 in peroxides eg: h2o2) so 4x-12=-2 , this implies 4x=+10, this implies x=+10/4 , x=2.5 so for each sulphur atom the oxidation number is 2.5 but generally sulphur exists as s2 so the oxidation number of sulphur(s2) is +5...;).

But before going on detail, let me clarify one thing taken from your sentence: "If oxygen is always -2" Let's correct this sentence. JC. because O is more electronegative than S, it will take all of the electrons involved in bonding. Books. Therefore, the oxidation number of O in peroxide ion is -1. Unfortunately there are some exceptional cases which are very difficult for students. How many grams of ammonia, NH3, are produced in the reaction with 50.0 g of N2, nitrogen? . With 6 oxygens, you have 6 * (2-) = 12- To get a total charge of 2-, the sulfurs must combine to give 10+. Since the total oxidation state for tetrathionate is -2, and there are six oxygens, each with an oxidation state of -2 for a total of -12, the sum of the sulfur oxidation states has to be equal to -2 - (-12) = +10. Microbial oxidation of sulfur is the oxidation of sulfur by microorganisms to produce energy. 0 0. (2) There is a compound which is formed by oxygen and fluorine, which is oxygen difluoride, OF2.
