Unformatted text preview: The emission spectrum of hydrogen was also observed. From the wavelengths observed, an energy diagram was created representing the energy amounts that can be emitted by a hydrogen atom. The energy was determined using the following formula: E=hν=hcN A λ Wavelengths of 430, 480, and 660 were observed, which correspond to photons with energies 278, 249, and 181 kJ/mol. Conclusion: The identity of the unknown salt solution could be determined by combining known emission spectra and comparing it to the solution’s spectra. After comparing several emission spectra, the unknown salt solution (number 3) was determined to be a mixture of sodium chloride and strontium chloride. The energy level diagram for hydrogen could be constructed by recording wavelengths observed in the emission spectra and plugging them into the equation for the energy of each photon....
