Question

Which reaction involves a redox process where the reducing agent contains a halogen?

Choose one · Correct answer highlighted

2Na + O₂ → Na₂O₂ S + O₂ → SO₂ 2NaI + MnO₂ + 2H₂SO₄ → I₂ + MnSO₄ + 2H₂O + Na₂SO₄ Correct 2H₂O₂ → 2H₂O + O₂

In 2NaI + MnO₂ + 2H₂SO₄ → I₂ + MnSO₄ + 2H₂O + Na₂SO₄, NaI (I: -1 to 0) is oxidized, reducing Mn (+4 to +2).
