In a Chemistry lab experiment, typically, a solid chloride unknown (not the AgCl product) for analysis is dried in an oven to remove adsorbed water before the analysis. How would the % Cl determined be affected (Would the calculated %Cl be too high or too low?) if the unknowns had not been dried? Explain.

Sample #1 has an absorbance of 0.300. Sample #2 is the same substance and has an absorbance of 0.600 using the same equipment. What is the relative concentration of the second sample? Select one: a. The concentration of sample #2 is the square root of that of #1. b. The concentration of sample #2 is that of sample #1 squared. c. The concentration of sample #2 is half that of sample #1. d. The concentration of sample #2 is twice that of sample #1.

Name: 11. A student is instructed to determine the concentration of a solution of CoCl2 based on absorption of light (spectrometric/colorimetric method). The student is provided with a 0.10 M solution of CoCl₂ with which to prepare standard solutions with concentrations of 0.020 M, 0.040 M, 0.060 M and 0.080 M. (a) Describe the procedure for diluting the 0.10 M solutions to a concentration of 0.020 M using distilled water, a 100 mL volumetric flask, and a pipet or buret. Include specific amounts where appropriate. Percent Transmittance The student takes the 0.10 M solution and determines the percent transmittance and the absorbance at various wavelengths. The two graphs below represent the data. 100 Absorbance 50 60 40 20 Absorbance 360 0.60 0.20 360 0.30 0.20 0.10 440 480 Wavelength (nm) 0.020 Wavelength (nm) (b) Identify the optimum wavelength for the analysis. The student measures the absorbance of the 0.020 M, 0.040 M, 0.060 M, 0.080 M and 0.10 M solutions. The data are plotted…
