Answer One of the two questions below or on back of page
1. In the Le Chatelier's Principle lab, Part II, you added NaOH to the solution. You observed a shift of equilibrium with addition of this solution. There are two different "ways" (actually two different substances) you can use as the stress in your explanation of why equilibrium shifted. Please explain how you go from NaOH to the stress substance and how it shifted the equilibrium if you started just with chromate (CrO42-.
2. In the Reacting Iron with Copper (II) Sulfate pentahydrate Lab, from your calculations which of the two reactants is the limiting reactant. What observation(s) in the lab supports your calculation of which reactant was limiting reactant? Explain? If your experimental observations does not support your calculation, explain why it does not support it including lab observations and what you should have seen.
