Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.

Roberta decided to find out the content of nickel (Ni) in a sample. She dissolved the 0.0882 g sample in about 30 mL of nitric acid, and after adding an excess of 8- hydroxyquinolinol (HQL), she diluted the solution with deionized water to a final volume of 250 mL. This final solution showed an absorbance of 0.694 at 365 nm, the wavelength of maximal absorbance of the Ni (HQL) complex, when measured in a 1.00 cm cuvette. Knowing that the trendline from the calibration curve for the Ni(HQL) complex at 365 nm is y = 1500x + 0.029 and that the atomic mass of nickel is 58.693 g/mol, calculate the percent content of Ni by mass in the sample. What is the % nickel by mass in the sample? (a) 5.31 percent (b) 7.38 percent. (c) 7.70 percent. (d) 7.4 percent. (e) None of these
Spectroscopy and a Calibration Curve Prepare a series of standard solutions of the colored compound with known concentrations by diluting the stock solution with distilled water. Use volumetric flasks to ensure accurate dilutions. Let's assume we have a stock solution of potassium permanganate (KMnO4) with a concentration of 0.100 M (molar). We will prepare five standard solutions with the following concentrations by diluting the stock solution with distilled water: 0.020 M 0.040 M 0.060 M 0.080 M 0.100 M Measure the absorbance of each standard solution at the wavelength of maximum absorbance (λmax) using the UV-Vis spectrophotometer.

2. ] You make 150.0 mL of a copper(II) sulfate solution but forget to cover it before leaving for the day. The next class, you measure the volume and find that you only have 132.0 mL remaining. You didn’t record the initial concentration, but you measure the absorbance of the remaining solution at 620 nm and find that it is 0.386. You also construct the following calibration curve for CuSO4: Standard solution Abs620 0.50 M 0.424 0.40 M 0.336 0.30 M 0.247 0.20 M 0.159 (refer to image) a. What is the value for k (in Beer’s Law)?

B. Quantitative Spectroscopy Prepare two graphs, %T vs. Concentration and Absorbance vs. Concentration, using the data for the cobalt standards. The concentrations of Cobalt standards 2-4 can be calculated using simple dilution calculations. Concentration should be on the x-axis for each of these graphs. The first should clearly show some curvature while the second should be a linear curve. Using the absorbance graph you can determine the concentration of the unknown. Take the absorbance value for the unknown and find that value on the y-axis. Draw a horizontal line from that point on the y-axis to the plotted line. From the point where the horizontal line intersects the plotted line, draw a vertical line straight down to the x-axis. Record the value from the point where you hit the x-axis as the unknown concentration.
