| Problem: What are the characteristic light emissions of varios metal? Procedure: 1. Bend a paper clip into a wire loop. 2. Place the wire loop into the chemical. 3. Place the wire loop into the crucible tongs. 4. Place the wire loop into the hot part of the bunsen burner flame. 5. Observe the color given off. 6. Repeat the other metals without contaminating chemicals. 7. Fill in the data chart. Information: Color wavelength Violete 410. nm Blue 470. nm Green 520. nm Yellow 580. nm Orange 600. nm Red 655.nm Red-Orange 620. nm Data Chart: Metal formula Color wavelength frequency energy Stronium SrCl2 Red Calcium CaCl2 Orange Copper CuCl2 Green Lithium LiCl Red-O Potassium KCl Violete Sodium NaCl Yellow Formulas: wavelength= S.O.L./Frequency S.O.L. = 3.00*10^8 m/s Energy= Hertz* frequency Hertz = 6.625*10^-3 J.s Safety Notes: 1. Wear your safet goggles. 2. Wear an apron. 3. Do not burn yourself. |
