I. Atomic Spectra Exp. 10 Date Performed: 3/31/11 Name: Breanna Jameson Date Submitted: 4/7/11 Lab Partner: Dennis Doyle Chemistry 1045L-35 Tong Chen II. Purpose This lab allows us to learn how to use a spectroscope and to learn how to interpret a spectrum. In the experiment we determine the spectra of several unknowns. Then by using the “bright line” spectra we will be able to identify the unknown ions.
