    Start by writing out the redox reaction equation for the nitrite ions and permanganate ions by combining these two.

    Permanganate reduction: 8 H+ + MnO4− + 5 e− → Mn2+ + 4 H2O
    Nitrite oxidation: NO2- + H2O → NO3- + 2H+ + 2e-

    This should give you the ratio of nitrite ions that react with the permanganate.
