Experiment 14 Fishkill Lab Zachary Earl Kort Zarbock Lab Section #16 March 9 th , 2016
Introduction
h being Planck’s constant, 6.63 x 10^-34 J*s, and v being frequency, or c/λ (speed of light 3.00 X 10^8 m/s over wavelength in nanometers)Absorption spectroscopy will be used to test for how much Cu(II) and Fe(III) is in the lake sample. Using complexing agents, in our case thiocyanate, SCN-, we can determine smaller concentrations of these ions. Absorption spectroscopy is used for colored solutions due to the fact that the electrons are excited to the 3d or 4d energy levels.In order to figure out the amount of metal in a colored solution, we measure out dilutions, given by the equation:M1V1=M2V2M1=original molarity/ppm/concentrationV1=original volumeM2=adjusted concentrationV2=adjusted volume
