Homework Help: Chemical equilibrium

  1. Feb 25, 2009 #1
    an equilibrium exists between chromate ion and the dichromate ion when potassium chromate is dissolved acid. the net ionic equation describing this reaction is given in the follwering equation:

    2 CrO4^2- (aq) + 2 H3O^+ (equilibrium symbol) Cr2O7^2- (aq) + 3 H2O (l)

    a student studying this equilibrium begins w/ an equilibrium mixture that is light orage in color.

    a. what change will the student observe when a solution of H2SO4 is added to this mixture at equilibrium?

    b. briefly explain the above answer

    c. what change will the student observe when a solution of NaOH is added to another example of this solution at equilibrum. why?
