Table 1: Resulting Fluorescence Colors and Appearances
Table 1 displays all of the results of the fluorescence colors and appearances, organized in a pattern of the buffers (1, 2, 3, etc.).
There were not too many significant trends in our data. The solutions resulting in a blue fluorescence ranged from 12-22.5% Manganese, and the solutions with an orange fluorescence ranged from 6.25-50% Manganese. This suggests that, because the higher Manganese concentrations typically result in the orange color, concentrations dictate the fluorescence. Because our sample size was so small, it is difficult to determine if such factors were actually responsible for the results. Among the buffers, two of those containing NaCl (solutions 1 and 6) were most effective in producing orange fluorescence. The pH 5 solutions produced the most orange solutions out of all (5/7). The trial would have to be expanded to determine whether these trends would continue with a larger number of solutions.
Additionally, all of Ben and Gabby's solutions fluoresced blue, 2/4 of Desi's were blue, and all of Julia and Nicole's solutions fluoresced orange. This raises the question of whether technique and overall amounts can contribute to the fluorescence; it is believed that Gabby and Ben's overall solutions might have been half the volume of Desi, Julia, Nicole, and Dr. Harting's, but the concentration values are all valid.
The questions we have include whether adding more Manganese would always lead to orange fluorescence, whether pH plays a large role in fluorescence, and what would happen in solutions with similar Manganese and Zinc values because only one solutions was close to 50% Manganese. These questions could possibly be answered by expanding the study.
