6. The nitrite ion (NO₂) in potassium nitrite is changed to the nitrate ion by the action of potassium permanganate (KMnO4) in sulphuric acid solution. 5 KNO₂ + 2 KMnO4 + 3 H₂SO4------> 5 KNO3 + 2 MnSO4 + K₂SO4+3 H₂O How many grams of KMnO4 are needed to carry out this reaction on 11.4 grams of KNO₂?
