Results and Discussion The results on the attached supplementary materials are the wavelengths of the various substances burned and measured with a spectrometer. For these results my group used the digital spectrometer attached to a computer in the lab. During the portion of the lab where a known mixture was created and tested, the results attained were not those expected by the group and myself. We used Potassium Chloride and Calcium Chloride. We expected the spectrum to include all wavelengths of both solutions, where as instead it only showed a few of some of them. This was quite the disappointment. However, we attributed these strange readings to contamination of the substances or malfunction of the

Unformatted text preview: tools used in the process. The idea of the mixed wavelengths readings was still used in the procedure to study and identify our unknown. Our group decided to use unknown salt mixture #3, but due to inconclusive results, we decided to try another salt solution. This time we used unknown #2 and this one seemed to lack contamination. We got very strong and defined peaks and a lot of different wavelength readings. Upon thorough analysis of the results we discovered that the wavelength readings contained the same peaks as Strontium Chloride and Sodium Chloride. We determined that this is what unknown solution #2 must be made of. During the lab we observed a discharge tube filled with hydrogen and collected data for the process of creating an energy-level diagram. Conclusion :...
