Homework Help: Laboratory Chemisry Question - Redox Reaction

  1. Oct 6, 2008 #1
    1. The problem statement, all variables and given/known data

    1. Explain why the following chemical reaction would not be effective to determine [Fe2+] in a given solution.

    Fe2+ (aq) + H2O2 (aq)-> Fe3+ (aq)+ H2O(l) | in acidic solution

    2. Relevant equations

    3. The attempt at a solution


    I am thinking that there may be a lack of colour change to indicate the stiochiometric endpoint of the redox reaction. I know that hydrogen peroxide and water are both clear and colourless in solution.

    However, I do not know the colours of Fe2+ and Fe3+ in solution.

    Thank you in advance!

    Endpoint detection can be done with some instrumental method, so it should be not a problem (although listing it won't hurt). However, what do you know about hydrogen peroxide stability?
