Purpose: The purpose of this lab was to see how different compounds can change color while in a flame and with this color, you can identify the compound.

Pre- Lab:
3.
a. LiCl 6.94 + 35.45=42.39 g/mol
b. BaCl2 137.33 + 35.45(2)= 208.23g/mol
c. CaCl2 40.08 + 70.9 = 110.98 g/mol
d.KNO3 39.10 + 14.01 + 16(3)= 101.11 g/mol
e. NaCl 22.99 + 35.45= 58.44 g/mol
f.SrCl2 87.62 + 35.45(2)= 158.52 g/mol

Data:

|Element |Red |Orange |Yellow |Green |Blue |Violet | |Lithium |1 |2 |1 | |3 | | |Barium |1 |2 |1 |2 |4 | | |Calcium |3 |1 |1 |3 | | | |Potassium | |1 |3 |3 |3 |2 | |Sodium | | |1 | | | | |Strontium |1 | |2 |3 |4 | |

Calculations/ analysis:

1. The term Ground state means the lowest energy state an atom or other particle has. The term Excited state occurs when an excited atom contains more energy than it does in its regular state. (Usually, after an atom has excited, it "calms down" and goes back to ground state.)
