Part A1: Do you notice any pattern in the color of the light used to detect absorbance (preset) and the color of the solution? If so, describe the pattern. What happened to the transmittance when the wavelength being detected was changed to approximately the same color as the solution? Try to come up with an explanation for this. How does the percent transmittance of the preset wavelength compare to the percent transmittance when looking at the transmittance over the entire visible spectrum? What happened to the transmittance when the width of the sample was changed? Explain why this makes sense. Explain why there was an upper maximum on the concentrations for each solution. What would happen to the absorbance or percent transmittance of a sample above that concentration? If you needed to measure the exact concentration of a solution whose concentration is above that limit, is there anything you can do?
