Balance the following equation in acidic medium: MnO4−+Fe2++H+→Mn2++Fe3++H2OMnO_4^- + Fe^{2+} + H^+ \rightarrow Mn^{2+} + Fe^{3+} + H_2O. What is the stoichiometric coefficient of H+H^+?

  1. A.8Correct answer
  2. B.5
  3. C.6
  4. D.4

Solution

The balanced ionic equation in acidic medium is: MnO4−+5Fe2++8H+→Mn2++5Fe3++4H2OMnO_4^- + 5Fe^{2+} + 8H^+ \rightarrow Mn^{2+} + 5Fe^{3+} + 4H_2O. Thus, the stoichiometric coefficient of H+H^+ is 8.
