Station #8 Flame Tests Standard 4b: Students know that the sun is one of many stars in the Milky Way Galaxy and that stars may differ in the size, temperature, and color. Materials: Textbook, alcohol burner, 4 inoculating loops, 4 liquid chemicals, beaker of water, goggles. Introduction: When compounds of certain metals are heated, the metals give off wavelengths of visible light. Each wavelength is unique to that element. Astronomers analyze the white light from stars, which when using a spectroscope, spread out the light into different colors of a spectrum. Dark bands appear in the spectrum caused by the absorption of the light by certain chemicals in the stars atmospheres. Each chemical has its own pattern of lines like a fingerprint. We will not use a spectroscope to analyze chemical flames, but we will use the flame test to detect certain metal ions. Procedure: 1. Put on your goggles. 2. Put your looped wire in the flame and burn off any residual chemical. Let cool. 3. Dip the loop in the liquid chemical and hold in flame. 4. Write down the color of the flame. (Your flame colors should be either green/blue, red, orange, or lilac) 5. Dip the loop in water. Completely burn off the previous chemical from your wire before you start the next chemical. 6. Repeat the step for all the chemicals 7. Then do the same step for the unknown. Determine which metal is present. 8. Put out your flame, then take off your goggles. 9. Wash your hands!! 83. What was the flame color for Copper Sulfate? 84. What was the flame color for Potassium Chloride? 85. What was the flame color for Strontium Chloride? 86. What was the flame color for Sodium Chloride? 87. Do a flame test for the unknown. Based on the color of the flame, what element is the unknown?
