FC: Sunshine Christian Bilingual School | 10 grade Mr. Jose Popoff Chemistry Lab - Energy of electrons Victor Ariel Vasquez mar/9/12
1: Introduction | In this lab report we are going to talk about electromagnetic radiation which are the main main characteristics of this form of energy, Emission spectra,Absorption spectra and continuous spectrum.
2: fling | Goals | Observe how a simple diffraction grating spectroscope operates | Observe and draw the spectra of several elements
3: Materials | Bunsen burner chloride salts of lithium, potassium, strontium, sodium, calcium, and copper (ll) diffraction grating spectroscope incandescent light matches presoaked wooden splints
4: Procedure | 1. Observe a continuous spectrum by looking at an incandescent light with your spectrometer. Note the calibration marks (400-800 nm) along the bottom of the box for lithium chloride in the Data section.
5: 2. Light your Bunsen burner. Adjust the burner until it produces a blue or colorless flame. | 3. Dip a presoaked splint into the lithium chloride. | 4. Have your lab partner look throught the spectrometer at the flame. Put the tip of the splint in the flame long enough for the salt to burn.
6: 5. Have your lab partner observe the spectrum that forms. Remoisten and redip the stick if necessary. Sketch the spectrum at the appropiate
7: calibration marks. Either label or color the bright lines to identify them. Switch roles with your lab partner so that each of you observe the burning splints using the spectrometer. | 6. Repeat steps 3-5 for the remaining known salts and an unknown salt, using a new splint for each test.
