Assume that you have an "X" solution that you do not know its concentration. But you have other X solutions with known concentrations and you know X solution absorbs maximum light at 575 nm. To calculate the unknown solution concentration, you have done some spectrophotometric measurements and obtained data given below. a) Prepare a standard curve by using the absorbance of known concentrations b) Calculate the concentration of unknown. Table 1: Absorbance of X solution (575 nm) Concentration (mg/ml) Absorbance 0.025 0.220 0.050 0.440 0.100 0.760 0.150 1.250 0.200 1,460 unknown 0,640

You left a glass full of homogenized milk on a table undisturbed for half an hour. What would result if you shined a laser beam against the side of the glass? * The beam of light will be reflected back to its original source. No light will pass through the two side of the glass. A path of light will be visible from one side of the glass. The beam of light will not be reflected nor will it be visible.

If 79.75% of light passes through a sample, what is the absorbance of the sample? Answer to three decimals.
Why would a chemist using a spectrophotometer need to perform both a scan across all wavelengths and a scan at a specific wavelength?
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?
