Equilibrium expression

  1. Apr 10, 2010 #1
    1. The problem statement, all variables and given/known data

    Aqueous solutions of hypochlorous acid, HOCl, can be unstable due to the reaction:

    2HOCl <--> Cl- + ClO2- + 2H+

    (c) Write out the balanced reaction appropriate to basic solution corresponding to the reaction given above.

    2. Relevant equations

    K = [Cl-][ClO2-][H+]^2/[HOCl]^2

    3. The attempt at a solution

    This question is part of a bigger equilibrium constant experssions' problem. I have answered all the parts to this question, I just don't understand what they are asking for here in part (c)?

    The answer given is:

    2ClO- <--> Cl- + ClO2-

    I don't understand how they got to that?

    Think: what happens to the weak acid in a basic solution?
