FLAME COLOR LAB
The purpose for this experiment was to show us how electrons react and the level of energy that is contained within the electrons. This was also a hands on experiment and visual to see the different energy colors in the form of light.
Procedure: Make sure all flammable objects are away, that you and your partner know what to do, and make sure all shared material is available.
Pre-Lab Questions
1.) Red is the lowest, visible, energy light.
2.) Violet is the highest energy light that cannot be seen with the naked eye.
3.) Violet has the highest frequencies in the electromagnetic spectrum
4.) Red has the lowest frequencies in the electromagnetic spectrum
5.) According to Bohr's theories, the electrons in the metal ions are "excited" due to the absorption of quantum or multiple quanta of light.
6.) An electron in an atom that has absorbed some energy, which has put the electron into a higher energy state. An excited electron will usually decay back into its resting level and release a photon.
Compound Name Formula Flame Color Observations Control (Methanol) CH4O Blue w/ Orange Bits Slowly Dies Out Borax Na2B4O7 White Crystallized Powder, burns orange and green, dies out slowly, clearCopper Sulfate CuSO4Blue liquid, thin, crystal Turns into crystals. Burns blue/green Magnesium Sulfate
MgSO4 Raw sugar look. Crystallized, white Dissolves quickly, burns quickly, blue/orange, raging, very hot/bubbling. Strontium ChlorideSrCI2 fluffy, white, snow-like, powdery Burns red and blue, crackle sound, VERY hot, bright red Unknown (Borax) N/A salt, sugar, white powder fully green, turns orange, huge flame, and very bright
Conclusion:
I believe I learned more than I expected because I originally thought that we were only going to observe the color of the flames but instead we also had to identify an unknown element through the color (amount of energy in the electrons).
Discussion of Theory:
I actually have a theory where the lower frequency colors (red,orange,yellow) are much more faster and raging than the higher frequency counterparts (green,blue,purple) because the violet colored flames seemed to move a lot slower and more stable. The red flame seemed to be very quick and raging, which I believe wasn't a coincidence.
Error Analysis:
There were no real errors that could throw off the experience for anyone, all of the errors were procedure based and didn't happen because of how strictly the rules were enforced.
Post Lab Questions:
1.) When the electrons are subjected to a flame, the electrons are extremely high in energy (electrons excited) and once they began to reform into a stable state they emit that energy in the form of light.
2.) A bond between a metal and nonmetal is an ionic bond because
Metal-metal=metallic bond
Metal-nonmetal=ionic bond
Nonmetal-nonmetal=covalent bond
3.) Salts are ionic compounds that are formed from the neutralization of an acid and base. Salt is also electrically neutral.
a4.) A combustion of burning in which substances combine chemically with oxygen from the air, which results in flame, light, and smoke.
5.) Tips on matches containing oxidizers, potassium, or sodium chlorate, and a fuel (sulfate mixed) are chemically changed when friction is created. The potassium chlorate is reduces to potassium chloride, sulfur is oxidized to sulfur dioxide and the organic compound is burned into carbon dioxide/water.
6.) A process that involves rearrangement of the molecular or ionic structure of a substance
7.) Wildfires can affect the wind currents of certain places and burn down animal shelters. Wildfires can also burn down crops and food that animals and even people will need in order to survive. Wildfires can affect many animals in terms of difficulty breathing and being burnt etc.
8.)
A. San Diego fires forced people to evacuate their homes leaving many valuable items behind.
B. Houses were burned down along with all the items,pictures, and many other valuable items to the family affected.
C. The air quality was affected and smoke was very present in the atmosphere
