paper) Post lab Questions 1. Explain what is meant by an equilibrium constant. Was the value constant for all your experiments? Should it be constant? Why or why not? 2. What does the calculated experimental value of the equilibrium constant, Ko indicate regarding the degree of completeness of the reaction? In other words, at equilibrium, were there mostly products, reactants, or relatively large amounts of both? Explain. 3. When you use a spectrophotometer, should you set the wavelength of light to be the same color as that of the solution, or would a different color be more appropriate? Explain. 4. What was the color of visible light chosen for this experiment? What was the color of the MGH ion? 48
