Flame Experiment

Chemistry Class

Why does the fire change its color? Are we putting the food color on the fire or gasoline to create colors flame?

The answer is NO.

The colors are changing because of the electrons get “excited” and produces the energy for the electrons to jump into different orbits and “fall back” to the ground. The photon that produces by those energy creates the wavelength that shows different colors on the flame.

To understand more about the flame, we did the experiments to see the quantitative and qualitative as the observation of the idea.

Flame Test Lap:


Safety goggles, wood splints, tongs/tweezers, Bunsen burner, test tubes with various compounds


  1. Safety goggles must be worn at all times
  2. Many of these salts are toxic. If you come into contact with any of the compounds make sure to notify the teacher and wash the contacted area thoroughly. Wash your hands before leaving the lab!


  1. Light the Bunsen burner (turn the gas on so you can just hear it, then use the striker)
  2. Place the wood splint for each compound into the flame using tongs or tweezers- ONE AT A TIME!
  3. Take note of the color of the flame and return the wood splint to the solution.
  4. CLEAN UP YOUR STATION! Carefully put the stoppers back on the solutions! Make sure the station looks like it did when you started! Let me know if you need new splints!
  5. Wash your hands thoroughly before leaving the laboratory
