Manganese Dioxide Precipitation

MnSO₄ + 2NaOH + H₂O₂ → MnO₂↓ + Na₂SO₄ + 2H₂O

Descripción general

Manganese(II) sulfate is oxidized by hydrogen peroxide in basic solution to form a dark brown precipitate of manganese dioxide. Mn is oxidized from +2 to +4. MnO₂ is highly insoluble and is a very effective catalyst for H₂O₂ decomposition.
