    Given the following standard electrode reduction potentials,
    ClO3- + 2H2O <- -> ClO- + 4OH- E° = +0.50V
    ClO- + H2O + 2e- <- -> Cl- + 2OH- E° = +0.89V

    Predict whether or not CLO- will disproportionate in alkaline solution to give Cl- and ClO3- according to the following reaction:

    3ClO- -> 2Cl- + ClO3-

    Solution Preview

    This problem is based on adding two equations. First, you know two Cl- ions are formed. This means the second equation needs to be doubled. In redox problems, doubling the reaction does not double to potential. It will stay at 0.89 ...

    Solution Summary

    This solution combines two reduction potentials to create an electrochemical equation and then judges whether or not a reaction will occur based on this equation.
