Solve que 22: 22. In dilute aqueous H2SO4, the complex diaquoudioxalatoferrate (II) is oxidized by MnO4 -. For this reaction, the ratio of the rate of change of [H+] to the rate of change of [MnO4 -] is Share with your friends Share 3 Vartika Jain answered this Dear Student, The reaction is,[Fe(C2O4)(H2O)]2- + MnO4- + 8H+ → Mn2+ + Fe3+ + 4CO2 + 6H2ORate of change of [H+]Rate of change of [MnO4-] = 81=8 -5 View Full Answer
