Flame Tests/ Light Emission Spectrum
Emission Spectra & Flame Tests
Intro
The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color, it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope, it is possible to observe the line emission spectrum produced by sunlight, artificial light, and various other gases. The operations performed relates to the bands of light and wavelength studied in class.
Procedure
In part one of the lab, a spectroscope is used to study the light emission spectrum emitted from sunlight, artificial light, and various other gases. To become organized; drawing boxes, collecting colored pencils, and picking a spectroscope is the first thing to do. After setting up the boxes, a spectroscope is used to study the light from outside, inside (artificial), and from three spectroscope tubes. It is detrimental to write down where each spectral line falls and what color it is, especially for identifying the unknown “D”. The spectroscope illustrates where each individual light’s spectral lines are apparent.
In the second part of the lab, flame tests are conducted on different metallic compounds. A Bunsen burner is used along with ten compounds to test to see which color is the strongest in each element’s spectrum. Three pairs of the compounds are the same. Each compound is soaked into a wooden stick. It’s important that not only does the stick not burn when testing the compound but also that the compound doesn’t drip and cause contamination. Colors that are emitted from the flame, when the metal in the compound reacted, are observed and noted.
Results
In part one, a spectroscope is used to see the line emission spectra in various types of light. Hydrogen, nitrogen and “unknown D” were observed in spectrum tubes while the
