Atomic Spectrescopy

Procedure: First, before starting anything, it was important to learn how to cave in the spectrometer and read it properly. Then, the spectrometer was mounted to a trap stand and pointed towards the burner. The next step was to clean an inoculating wire by immersing it into a beaker of DI water, then into a beaker of 3 M HCl, and then back into the DI water. After it was rinsed, it was then placed into the kindle to make sure no other colour in were being emitted. Then the wire was dipped into one of the lead solids and ruin in the Bunsen burner flame. While at the uniform quantify the colorize were discover in the spectrometer. This was done with all(prenominal) of the three solids. Then, hydrogen discharge was observed through the spectrometer, and its modify and positions were recorded.

Results: The side distinction results are the colors from the different solids burnt: Test provide #Colors of Line Emission SpectrumColor of flare out 2Orange, (red bureau dark to the left)Light purple/Orange 6Orange, (Red way stumble to the left)Bright Orange 7Green, Orange, RedRedish Orange The following results are the colors and wavelengths observed of the hydrogen spectrum: Colors of Line Emission SpectrumWavelength Red650 nm Green480 nm purplish/Blue430 nm Discussion: Colorfrequency (Hz)Energy of photon (J)Change in E (J)Rydbergs constant Red4.612 x 10^143.06 x 10^-19-3.06 x 10^-19-2.203 x 10^-18 Green6.246 x 10^144.14 x 10^-19-4.14 x 10^-19-2.208 x 10^-18 Purple/Blue6.972 x 10^144.62 x 10^-19-4.62 x 10^-19-2.200 x 10^-18 Average Rydberg Constant= -2.204 x 10^-18 Actual Con stant= -2.2 x 10^-18 stock parenthesis= .! 182% Calculations: Beaker N contained the test tubes 2, 6, and 7. Based on the colors emitted in the line spectrum, test tube 2 could peradventure be the metal K - potassium. It resembled very closely the very(prenominal) line spectrum and colors by having rather faint lines and a hardly a(prenominal) scattered brighter lights of orange and red. Test tube 6 could take a leak been...If you want to get a full essay, order it on our website: BestEssayCheap.com
