    The equation is:
    2CrO4(2-) (yellow) + 2H3O(+) = Cr2O7(2-) (orange) + 3H2O
    when adding HCl to the mixure - the color will become darker - chromate ions will react w/ the hydronium ion to form the orange color

    Now add salt to the above mixture - what will the color be (the mixture with the HCl) and explain your answer using LeChetalier's Principle.

    From there you add excess NaOH solution to the equilibrium mixture - what is the outcome?
