Follow-up Question

Your submitted reaction is unbalanced. In your reaction, there are 20 oxygen, 1

manganese atoms in the reactants but 24 oxygen, 2 manganese atoms in the products. Reconsider the coefficients in front of your reactants and/or products and try again. The following steps may help you balance this redox reaction in basic solution:

  1. Split the given equation into two half-reactions: one for oxidation and one for reduction
  2. For each half-reaction, balance all atoms except H and O on both sides of the equation by altering the coefficients.
    1. Balance O by adding H2O to the appropriate side of the equations as needed
    2. After adding H2O, balance H by adding

    H+ to the appropriate side of the equation as needed

    1. Determine the number of electrons (e) lost or gained in each half-reaction and add e to the appropriate side of the equations to balance charge.
    2. Add OH to both sides of the equation to neutralize all of the H* by forming H2O
    3. Cancel out water molecules that appear as both reactants and products
    4. Multiply each half-reaction by whole numbers as needed to make the same number of electrons appear in both half-reactions
    5. Add the two half-reactions and ensure that electrons completely cancel out.
    6. Simplify the equation by cancelling out species that appear on both sides.
