Various Color of Light as the Effect of Electron Emission
Objective
Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify the unknown metallic ions by means of its flame tests.
Background
When atoms absorb energy, electrons move into higher energy levels, and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light is made up of a mixture of all the wavelengths of light. Light, consisting of waves consists of wavelength and frequencies that are inversely proportional to each other, so as the wavelength of light increases, …show more content…
During a flood, the labels from three bottles of chemicals floated away. The unlabeled bottles of white crystals were known to contain the following:
* Lithium sulfate
Lithium sulfate would give off a pink flame when lit, making it easy to identify and relable against the other substances. * Potassium nitrate
Also, potassium would give off a light purple color when lit, making it simple to identify against the other substances. * Ammonium chloride
Ammonium, although not tested in this lab, would be easy to pick out since it most likely does not give off a pink or purple flame as lithium sulfate and potassium sulfate do, respectively.
3. Using the results of this lab, explain how one could easily relable these three bottles. (Tell me exactly how you would know what was in each. Write answers in the space next to each compound.)
We can conclude and compare the colors each substance gives off to the known solutions and choose the similar color.
4. List some common uses of the colors produced in flame tests.
A practical application of different flame colors in the presence of metals comes to play in fireworks. As different metals burn they produce the different colors, as mentioned, we see in a fireworks …show more content…
The lab was not infallible, however, as the samples could have been easily contaminated, mixed, or out of order. Also, burning the woods splints caused the flames to appear orange, affecting the results in several possible ways. The results seemed similar to each other and many of them seemed to share a slightly orange hue, perhaps because the splint was being burned unintentionally at the same time. The first unknown was identified as Calcium due to the similarities in color and the second unknown was identified as strontium for the same reason. For future experimenters, the solutions should be labeled so that in the future, the chance for error is dramatically
