What wavelengths are associated with the light color observed in each metal's flame test? 2. What are the most probable atoms in your unknown solid based on the observed light emissions? 3. Sodium light is easy to filter because it only emits light at a specific wavelength. Would any of the other metals you tested also be easy to filter? Why or why not? 4. If a fireworks engineer was planning a Christmas show and wanted to create a red explosion followed by a green one. Based on the flames observed, which metal salts should they use

These 6 unknown compounds need to be identified (column on right is active ingredient): Sugar sucrose Cornstarch Cornstarch Rolaids CaCO3 Epsom salts MgSO4 Salt NaCl Salt Petre KNO3 Here are the tests that can be conducted: PbNO3 (aq) test BaCl2 (aq) test 1M NaOH (aq) test Acetic acid (aq) test Flame test test I only need help with identifying sugar, Epsom salts and salt petre. Which of the above tests can identify them? If you pick flame test, choose which color the flame will be when conducted with each of the 6 compounds (options are no colour, purple flame, white flame, green flame, orange-yellow flame).
