Observations and Interpretations 1) Balance the chromate / dichromate equilibrium equation: CrO42-(aq) + H+(aq)  Cr2O72-(aq) + H2O(l) (unbalanced equation) 2) What was the original color of the K2CrO4 solution? If the above equilibrium is established in the original solution, which species, CrO42-(aq), or Cr2O72-(aq) appears to be present in greatest amount? 3) What color did you observe after adding the 3M H2SO4 solution? 4) What color did you observe after adding the 1M NaOH solution? 5) Assume that the dynamic equilibrium represented in the equation in 1 is present in the original solution you placed in the test tube. Based on LeChatelier’s Principle, as stated above on page one, you will interpret the observations made in 2, above: (Notethat H2SO4 produces H+ in solution.) a) When sulfuric acid was added, which reaction (forward or reverse) was favored?
