What is the reduction half-reaction for the reaction between iron(II) sulfate and potassium permanganate in a sulfuric acid solution?
5Fe²⁺(aq) + MnO₄^-(aq) + 8H⁺(aq) → 5Fe³⁺(aq) + Mn²⁺(aq) + 4H₂O(l)

Question

Quizplus · Accepted Answer

The reduction half-reaction involves the reduction of the permanganate ion (MnO4-) to the manganese ion (Mn2+). The balanced reduction half-reaction is:

MnO4-(aq) + 8H+(aq) + 5e- → Mn2+(aq) + 4H2O(l)

Therefore, the correct answer is B, which shows the reduction half-reaction for the permanganate ion.
