Calculate the Oxidation number of Sulphur in S 2 O 8 2-ion. What is the oxidation number of S in Na2S4O6? Log in. (as per suggestions). About Logiquest; About Kaplan. Since the part has a change of -1, the total oxidation numbers = 0 (Total oxidation numbers of O) + (Oxidation number of S in blue) = -1 (-2) × 3 + (Oxidation number of S in blue) = -1. The central sulfur atoms, those bonded to oxygen each have an oxidation number of +6 and the two bridging sulfur atoms each have an oxidation number of -1. (a) 3/5 (b) 3/2 (c) 2/5 (d) 5/2.
