Flame Test Lab
Flame Test Lab
Period 2
Due: 10/19/11
Honors Chemistry
Purpose/Objective: To observe the colors produced when elements are put into a flame and to prove when electrons jump down from higher layers they release energy in the form of light.
Materials:
CoCl2
Na2SO4
CaCl2
KCl
SrCl2
CuCl2
LiCl
Unknown A
Unknown B
Distilled H2O
Q-tips
Beaker
Bunsen Burner
Spectroscope
Spot Plate
Procedure:
1. Light the Bunsen Burner.
2. Fill a beaker with water.
3. Get the spot plate with all the known and unknown salts.
4. Get a Q-tip and dip it in the beaker.
5. Dip the Q-tip in CoCl2.
6. Hold the Q-tip over the flame until it starts to turn black. Record your observations.
7. Repeat this process for all of the other salts. (CoCl2, Na2SO4, CaCl2, KCl, SrCl2, CuCl2, LiCl, Unknown A, and Unknown B.
8. Repeat the process again to make sure you recorded everything correctly.
Data:
Compounds
Observations CoCl2
Before putting it into the flame, the CoCl2 was a red solid that looked like tiny crystals at room temperature. After putting it in the flame, the CoCl2 turned the flame purple and there were many sparkles. Na2SO4
The Na2SO4 was a small white solid particle at room temperature before the flame. Putting it into the flame caused the flame to instantly turn orange-yellowish. CaCl2
The compound CaCl2 was a white, hard, and chunky substance at room temperature prior to burning it. Holding it in the flame caused the flame to turn red-orange and Q-tip to burn quickly. KCl
KCl was a small, clear solid substance at room temperature before putting it in the flame. Putting it in the flame made it turn pink-orange. There was also a tiny amount of sparkles. SrCl2
Prior to putting the SrCl2 in the flame, it was a small white particle that resembled salt at room
