What is the reason for calibrating the UV spectrophotometer with distilled water? To check if the spectrophotometer works correctly. To determine the maximum absorption wavelength . To predict which color the solution will absorb based on the color wheel. To obtain accurate absorbance measurements. 4 points Why is it necessary to plot a calibration curve for the standard solutions? To determine the uncertainty in the absorbance measurements for each solution. To determine the maximum absorption wavelength . To confirm that the absorbance varies inversely with the concentration according to Beer's Law. To obtain a linear equation of the line, which is used to calculate the concentration of in the unknown sample. 2 points From the equation of the line, what two values can be obtained from the slope? Molar absorptivity and path length (I). Absorbance (A) and molar absorptivity . and absorbance. Path length (I) and . 4 points 152.0 mL of a solution was diluted to . Calculate the final concentration of this solution. Type your answer... 4 points A calibration curve gives a slope of . If the path length equals , calculate the molar absorptivity . Round your answer to PLACE. Type your answer... 4 points your answer to 1 DECIMAL PLACE. Type your answer...
