1. The following table was filled by the student during the measuring of the absorbance of a 100 mM solution of Ni2+ ion. Wavelength Absorbed (nm) Color Absorbed Color Observed Absorbance of solution 410 Violet Yellow-Green 0.23 430 Blue-Violet Yellow 0.52 480 Blue Orange 0.07 500 Blue-Green Red 0.03 530 Green Purple 0.01 560 Yellow-Green Violet 0.01 580 Yellow Blue-Violet 0.01 610 Orange Blue 0.03 680 Red Blue-Green 0.16 720 Red-Purple Green 0.19 Select a correct wavelength to measure the absorbance of nickel-containing solutions and justify your answer below 2. The following calibration table was built in order to calibrate the colorimeter: Blank 0.000 0.00 Test tube 1 0.020 0.15 Test tube 2 0.040 0.26 Test tube 3 0.060 0.37 Test tube 4 0.080 0.46 Test tube 5 0.100 0.55 Test tube 6 0.120 0.66 Test tube 7 0.140 0.72 Test tube 8 0.160 0.84 Test tube 9 0.180 0.94 Test tube 10 0.200 1.05 Report the equation of your calibration curve (trendline) in terms of Absorbance, Molarity, and Molar Absorptivity (you do not need to show the graph) and the value of R2 Calibration Curve Equation The value of molar absorptivity with units The value of R2 The 18.0 g sample of Zn-Ni alloy was dissolved in the nitric acid and diluted to 250.0 mL. The measured absorbance of the solution was 0.77. Use the calibration curve equation to calculate and report the molarity of the solution and % nickel in the alloy.
