It is also called Marshall's acid. are solved by group of students and teacher of Class 11, which is also the largest student community of Class 11. And as is typical the sum of the oxidation numbers of each constituent element equals the charge on the molecule, i.e. 1 answer. Calculate oxidation states of sulphur in the following oxoacids of S: H2SO4, H2SO3, H2S2O8 and H2S2O7. O O. H- O- S- O - O- S-O-H. II link ii . The oxidation number is synonymous with the oxidation state. The structure of H2S2O8 is given by-O O. II peroxy II . and in the 2 nd case NA2S4O8 , in thaat case take sulpher o.n to be x after that , 2(1) +4(x) + 8 (-2) =0 so, by calculating the value of x u will get sulpher will present in a oxidation state of 3.5 coming to the 3 … What is the oxidation state of S in H2S2O8. Determining oxidation numbers from the Lewis structure (Figure 1a) is even easier than deducing it … Hence it can form SCl4 but not SCl6. 1 decade ago. What is the oxidation number of S in h2s2o8? Find the oxidation number of S in K2S2O8. In thiosulphate, two sulphurs have oxidation state of -2 and +6. 0 3. Still have questions? 1 1. ali_zaidi. The oxidation state of Sulphur in H2S2O7 is +6. But there is an alternative formalism, which I will outline.....We gots "sulfuric acid", H_2SO_4, and here CLEARLY we got S(VI). Sulphur bonded to three oxygen is considered to have +6 (Sulphur A) and other sulphur has -2 (Sulphur B). Join Yahoo Answers and get 100 points today. 47. 1 answer. It is better to use the term Oxidation state or Oxidation Number. The Questions and Answers of Calculate the oxidation states of the sulphur in the following - i) Na2S2O3 ii) Na2S4O6 iii) H2S2O8 iv) S2O8 2-? Get your answers by asking now. in H2S2O8, since 2 oxygen is forming the peroxide linkage here , so, the o.n of sulpher will be +6 . Fluorine is the strongest oxidizing agent and it can oxidize sulphur to its maximum oxidation state +6 to form SF6. oxidation number is 2. Chlorine is not a good oxidizing agent, it cannot oxidize sulphur to its maximum oxidation state. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. (as per suggestions). It contains sulfur in its +6 oxidation state, but it also contains a peroxide group, which is why it appears to be in a higher oxidation state than sulfates. The oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds. asked Jun 13, 2017 in Chemistry by sarthaks (25.9k points) oxidation number; oxidation state +1 vote. In structural terms it can be written HO3SOOSO3H. Peroxydisulfuric acid is a sulfur oxoacid with the chemical formula H2S2O8. APPLYING THE RULES NOW-oxidation number of sulfur will be =+6. Chlorine can oxidize sulphur to only +4 oxidation state.
