Homework Help: The reducing agent in this redox equation?

  1. Jul 2, 2009 #1
    1. The problem statement, all variables and given/known data
    Which is the reducing agent in this equation, if any?

    Cr2O7 2- + 2OH- --> 2CrO4 2- +H2O

    2. Relevant equations

    3. The attempt at a solution

    After giving the elements their oxidation numbers I found the reducing agent to be Cr2O7 2-

    Is this correct?
