✔ 最佳答案
Half equation for the oxidizing agent (acidified permanganate ion):MnO4-(aq) + 8H+(aq) + 5e- → Mn2+(aq) + 4H2O(l) ... (1)
Half equation for the reducing agent (iron(II) ion):
Fe2+(aq) → Fe3+(aq) + e- ... (2)
To get the overall equation, (1) + (2)x5, and the electrons are eliminated:
MnO4-(aq) + 5Fe2+(aq) + 8H+(aq) → Mn2+(aq) + 5Fe3+(aq) + 4H2O(l)
