Based on your understanding of color's relationship to wavelength, identify the approximate wavelength of light (nm) emitted by strontium when it was burned. (No quantitative data was collected for this; you are giving an approximate value only, based on what you observed.) Explain your reasoning in full, making sure to cite specific data and observations to support your answer.
2. While boiling potatoes for dinner in salted water, the pot boils over and you notice that the flame on your gas burner turns to bright yellow-orange. How would you explain the appearance of a color in the previously blue flame?
3. What would you conclude about chloride based on results from the flame tests?
4. Place the metal solutions you tested in order of increasing energy based on the colors observed in the flame test; i.e., A < B < C.
