Homework Help: Balancing Oxidation-Reduction Reaction

  1. Nov 18, 2012 #1
    1. Complete and balance the following equations, and identify the oxidizing and reducing agents:

    2. Rules.

    1) an element that is reduced Gains electrons and loses Oxygen

    2) an element that is oxidized loses electrons but gains Oxygen




    3. My attempt

    Oxidizing Agent: 5e + 8H + MnO4 ^(1-) ---> Mn ^(2+) + 4H2O

    Reducing Agent: 2H2O + CH4O ---> H2CO2 + 6H ^(1+) + 6e
    --------------------------------------------------------------------


    At this point I relize that what I'm doing is totally wrong. I don't know how to solve this.

    4. Correct Answer from Book:

    4MnO4 ^(1-) + 5 CH3OH + 12 H ^(1+) ---> 4Mn ^(2+) + 5HCO2H + 12 H2O

    Correct.

    Oxygen is not balanced.
