In this lab, the measurement wavelength on the colorimeter was set at 470 nm. This measurement wavelength was the best choice available on the colorimeter but it was not the best chemical choice for measuring the absorbance of FeSCN2+. a. (5 pts) In terms of instrument sensitivity, explain why the choice of wavelength on the colorimeter is important. b. (5 pts) Since the wavelength setting was not the ideal wavelength (?max) for these absorbance measurements, do you expect the value for your absorbance readings to be too high, too low, or unaffected by the colorimeter setup? Explain. c. (10 pts) What experiment could you do, what data would you collect, and how would you analyze the data to determine the best setting for measuring the absorbance of FeSCN2+? Be sure to fully explain how your experiment and the resulting data would allow you to determine the wavelength of maximum absorbance for the FeSCN2+ complex.
