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?
