Chemical Reaction Lab Report
The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light. The excitement caused by heating makes the electrons jump from their ground state into a higher energy level. An electron can absorb the amount of energy that will promote it to a higher electric shell. When an electron goes into this state it becomes
both excited and unstable. Different chemicals have different elements with different arrangements of electrons. The arrangements of electrons determine the sizes of the quantum jumps which in turn decide each element’s emission spectrum. If all of the different elements have different arrangements of electrons, they each have a different emission spectrum. Therefore, two different chemicals would emit different colors of light. The chemicals need to be heated in the flame before emitting colored light because the electrons in each atom need to absorb enough light to cause them to jump from a ground state to an excited state and back to a ground state to emit colored light. This is a useful method for identifying unknown metals certain metals emit different light and if it is an unkown you would know. Some examples of colorful light emissions are street lights, neon signs and, of course, fireworks. Neon signs emit light when an electric current passes through the neon gas. The electric current excites the element’s electrons causing it to jump from a ground state, to an excited state, and back to a ground state. Fireworks emit light when a fire, such as the fuse, excites the different electrons in different metals. These light emissions are related because they both have to do with and element’s elec. The Flame Test expanded my knowledge of compounds by allowing me to know how to identify them. It was also fun because of the fact that we were allowed to use fire and enjoying the different color flames. I now know how to identify compounds because of this lab.
