Sulphur in + 3 oxidation state is present in. S4N~ + 6(0) + 10H20--~ 4H2SO~ + 4NH3 (2) The oxidation state of sulphur in sulphuric acid is +6; since twelve equivalents of oxidant are consumed to bring all the four sulphur atoms in sulphur nitride to this state, the average oxidation number of sulphur in sulphur nitride may be seen to be +3. In Wolff‐Kishner reduction, the carbonyl group of aldehydes and ketones is converted into. The ion is S=SO 2. Not formula A widely reported in textbooks, but the SH form B probably represents the correct structure of thiosulfuric acid.
