The oxidation number of Fe in Fe3O4 is fractional. Why?
Asked by Topperlearning User | 15 Apr, 2015, 14:41: PM
answered-by-expert Expert Answer

Fe3O4 contains Fe atoms of both +2 and +3 oxidation number. It is a stoichiometric mixture of Ferrous (FeO) and Ferric (Fe2O3) oxides combined  as FeO.Fe2O3. Therefore, the oxidation number found in such cases is average oxidation number.

(i) Balance the following equations by oxidation number method: (1) Cu + HNO3 → Cu (NO3)2 + NO2 + H2O) (2) K2Cr2O7 + HCl → KCl + CrCl3 + H2O + Cl2 (ii) Give reasons for the following: (1) HNO3 acts only as an oxidising agent while HNO2 can act both as a reducing agent and an oxidising agent. (2) Chlorine liberates iodine from KI solution. How will you convert the following? (Give balanced equation.) (1) Sodium acetate to methane Find the oxidation number of: (1) S in Na2S4 O6 2) S in S subscript 4 space O subscript 6 superscript 2 minus end superscript
