Unformatted text preview: Test Solution Wavelength (nm) LiCl and KCl 670 760 LiCl and SrCl 2 589 670 768 The emission spectra values for hydrogen were also taken, and the values appear in Table 4. Table 4: Emission Spectrum of Hydrogen Element Wavelength (nm) Hydrogen 655 485.3 433.24 The energy associated with each wavelength, E = N A hc l D E = (6.022 10 23 )(6.626 10- 34 )(3.00 10 8 ) 655 10- 9 D E = 183 kJ/mol E = 246.7 kJ/mol E = 276.30 kJ/mol was then used to construct a partial energy level diagram for hydrogen. Conclusion: Due to the similarities between the observed spectra of the unknown solution in Table 1 and the LiCl/SrCl 2 solution in Table 3, the unknown was determined to be a solution of lithium chloride and strontium chloride. A partial energy level diagram was drawn for hydrogen:...
