//Drexel University CHEM431 Analytical Chemistry II// For part A the students perform a Beer's Law analysis of a transition metal ion (Ni2+) in aqueous solution followed by a simultaneous analysis of a two-component mixture of Co2+ and Ni2+ (Experiment 6-1 supplemental from Sawyer, Heinemann & Beebe). In Part B they explore the effect of slit width on the vapor phase spectrum of benzene. Part A uses a Perkin-Elmer Lambda-35 instrument while part B utilizes a Perkin-Elmer Lambda-950, which is capable of significantly higher spectral resolution.
