Flame Tests Using an Improvised Alcohol Burner
Two unknowns were also tested.
Each solution provided a different colored flame.
Ba Yellow- green
Unknown A Red
Unknown B Yellow
From the DemonstrationProcedure taken from: Dragojlovic, V. Flame tests using improvised alcohol burners. Journal of Chemical Education (76)7, 929.
The sodium ion is the cation and the chloride ion is the anion
The color of the second unknown was yellow, therefore it was sodium.
When an electron “falls” it emits energy in the form of electromagnetic radiation.
The greater the n value, the higher the energy, the more stable the orbital.
The n value corresponds to the principle quantum number.
False. A red flame is indicative of Li.
False. The higher the n value, the less stable the orbital.
True.Miniquiz on Flame TestsTrue or False
