Homework Help: Redox Balancing

  1. Apr 24, 2007 #1
    1. The problem statement, all variables and given/known data
    Cl2 -> Cl- + ClO3-
    (in basic solution)

    2. Relevant equations

    3. The attempt at a solution
    Well, I've tried messing around with the half reactions but since Cl2 is involved in both, they don't seem to do much good.

    e + Cl2 -> Cl-
    Cl2 -> ClO3- + 5e

    Normally, I would multiply the top by 5e to let the electrons cancel, but then there's a Cl2 and a 5Cl2 so that doesn't appear to work...

    Anyone have any ideas on how to do this?
