UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

You wish to measure the iron content of the well water on the new property you are about to buy. You prepare a reference standard Fe3+ solution with a concentration of 5.74×10−4 M. You treat 14.0 mL of this reference with HNO3 and excess KSCN to form a red complex and dilute the reference to 60.0 mL. The diluted reference is placed in a cell with a 1.00‑cm light path. You then take 30.0 mL of the well water, treat with HNO3 and excess KSCN, and dilute to 100.0 mL. This diluted sample is placed in a variable pathlength cell. The absorbance of the reference and the sample solutions match when the pathlength is 1.76 cm. What is the concentration of iron in the well water? For each solution, the zero is set with a blank.
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.
