Discussion of Results: The lab went relatively smoothly. The only struggle was remembering which sample already completed, so there were multiple trials done for each element. There was no difference in the different trials. In their excited states, NaCl and CaCl 2 have orange flames. KCl has a pink flame. SrCl 2 has a red flame. BaCl 2 has a yellow flame. CuCl 2 has a green flame. The unknown received was unknown X. Conclusion: Unknown X in its excited state displays a yellow flame. BaCl 2 also emits a yellow flame. Therefore, unknown X is most likely BaCl 2 ....
