Flame Test lab

During the flame test lab there were some slight inaccuracies.  If there was too much oxygen running into the gas, the fame would be to big, to little would make it to small.  It was difficult to know which substances were unknown because they all had a reaction to the flame.  Identification of a substance with only one property is valid because we know exactly what is in the specific substance.  The flame turns color when one electron is pushed from one orbital to another.  The metallic elements used in the activity were

  • Kn03 - Potassium  
  • Sr(n03) - Sulphur
  • BaN03 - Boron
  • CuC12 - Copper
  • LiN03 - Lithium
  • CoCO - Cobalt

To heat up the reactants in the metal causing them to react by changing color.
