Purpose: To determine the colors of the Atomic Emission Spectra of several metallic ions. Materials: Safety glasses 10 test tubes Test tube rack Paper Pencil 50 mL beaker Bunsen burner Nichrome wire Barium Nitrate Copper Nitrate Strontium Nitrate Lithium Nitrate Potassium Nitrate Sodium Chloride Calcium Nitrate Unknown solutions A,B, & C Hydrochloric Acid Wash bottle (with distilled water) Procedure: 1. Label the test tubes with the names of the solutions and unknowns. 2. Place about 5 mL of …showed first 75 words of 488 total…

Lithium Nitrate burns purple/red. Potassium Nitrate burns pink/purple. Sodium Chloride burns bright orange. Calcium Nitrate burns red/orange. Strontium Nitrate burns red, orange, and yellow. If other compounds containing the same metal ions were flame tested, I think that they would burn the same colors, unless mixed with others.
