Flame test part 2

  1. 1. Flame Test
  2. 2. Involves placing the unknown element or compound sample to a flame to determine it’s identity through the flame color (emission spectrum).The flame would change its color depending on the metal ions present in the given element or compound.The color helps distinguish the given element from the others.Flame test
  3. 3. Flame gives energy to any element or compound.if any sample is placed through heat, its electrons would get “excited” , and its electrons would transfer to higher state from its ground state to excited state As the electrons emit that accumulated energy as they return to lower orbitals , photons are produced.Flame test
  4. 4. Through this chart, we can infer that:the closer the color is to purple, the higher the energy levels areFlame test
  5. 5. ProcedureBased on the given instruction on the Lab Manual
  6. 6.  Test tubes were prepared for the experiment in order to store the liquids, while HCL was then placed on an Erlenmeyer flask. Each chemical was then placed of each given test tube and labelled The nichrome wire was then dipped at a chemical , then was placed at the tip of the inner flame of the Bunsen burner, the change of colour of the flame was then recorded.Procedure.
  7. 7. Once it was recorded, the wire was then cleaned by HCL, after which the process of flame testing was done repeatedly until all samples was then tested and recorded.procedure
  8. 8.  After all of it are tested, an unknown liquid then was tested. Once the unknown liquid was determined by its flame colour it was then recorded.Unknown chemical
  9. 9. Element Colourpotassium pinkcalcium orangecopper greensodium- orangelithium Red orangebarium yellowstrontium redResults
  10. 10. The flame changed colour once the nichrome wire, with a solution was placed to the flame.The flame seems to be able to retains its colour, after the wire, with the solution is taken away from it.The wire is observed to not give any colour to the flame anymore right after HCL was used to clean it.Observations
  11. 11. Guide Questions
  12. 12. One difficulty found in the experiment is that there are some flame colors which are found very similar to the other.in order to avoid similarly colored flames, thorough cleaning of the loop and a restarting the test of the same colour is necessary.Difficulties found in theexperiment?
  13. 13.  flame is used because heat makes the metallic ions more energetic as it makes them transfer to higher states and also cause a reaction. The hottest part of the Bunsen burner is the tip of the inner flame because the heat found in the hottest and has the highest energy level compared to all the other parts of the flame.Flame
  14. 14. Ifthe sample has more than one metal, then the flame would emit colors which are mix from both components of that sample which makes the result seem confusing and unreliable.More than one metal component
  15. 15. Real life situations
  16. 16.  The metal components found in fireworks are reacted to the flame and creates color as it explodes. Mixing metallic properties is done here also such as mixing chemicals that make red and blue explosion in order to make a purple explosion.Fire works
  17. 17.  Forensic science uses flame as one of its methods in solving crime. Through conducting flame test on the victims blood, they would notice in the victim is poisoned or not , if it emitted a flame color found only on toxic elements or compounds like Barium.Forensic analysis
