post lab questions 1. is the flame color a test for the metal or for the chloride in each compound? explain your answer? 2. why do different metals have different characteristic flame test colors? 3. most salts contain a metal and a non-metal. look at the compounds we tested and determine whether it is the metal or the non-metal that is responsible for the color produced in the flame test for that salt. how can you be sure your answer is correct? 4. why do the chemicals have to be heated in the flame before the colored light is emitted? 5. could flame tests be useful in determining identities of metals in a mixture of two or more salts? if so, what problems might arise? if not, why not? explain your answer. 6. construct the line spectra for each metal used in the experiment. (can use pictures from the net with cut and paste. spectra must be in full color and only individual lines must be present. 7. using the one brightest (color) wavelength for each cation, select a wavelength value from the chart above
