Flame Test
Problem: What are the characteristic light emissions of various metals?
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
Violet 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 Violet
Sodium NaCl Yellow
Formulas: wavelength= S.O.L./Frequency S.O.L. = 3.00*10^8 m/s S.O.L. = speed of light
Energy= constant* frequency Constant = 6.625*10^-31 J.s
Safety Notes: 1. Wear your safety goggles.
2. Wear an apron.
3. Do not burn yourself.
