Unformatted text preview: Optical Spectroscopy by Rachel Soffer Lab Instructor: Kaushik Nanda Oct 24, 2007 Purpose: To design and implement an experiment capable of determining the composition of a solution that contains two or more ionic salts and to construct a partial energy diagram for Hydrogen Results and Discussion: Determining the composition of an unknown salt solution A spectrometer was set up and used to determine wavelengths of a florescent light spectrum, incandescent light bulb spectrum, helium spectrum, and 5 salt solutions. Results were tabulated (Table 1). Table 1: Wavelengths of emission sources Sources Wavelength (nm) Florescent light 405.07 Incandescent light bulb Continuous spectrum Helium 382.84, 389.89, 396.94, 403.60, 439.27, 447,68, 474.42, 493.37, 502.36, 505.24, 588.43, 668.93, 707.93, 729.57 NaCl 590.88, 767.53, 771.10 LiCl 590.53, 671.98 KCl 591.23, 767.53, 771.42 CaCl 2 590.00, 555.43, 619.33, 621.75, 767.85, 625.89 SrCl 2 607.57, 661.81, 676.38, 590.53, 683.80 NaCl and LiCl were combined to make a known salt solution and a spectrometer was used to determine its wavelengths. Results were tabulated (Table 2)determine its wavelengths....
