If more time for observation is needed, turn off the tube for ~15 seconds and then turn on for another 30 seconds. Use Table 1 in the Background section to record the approximate wavelength of light emitted for each metal in Data Table 2. Next, you will observe the light from different sources through the spectroscope and record the number, color and wavelength (in meters) of the lines of light in your data table… It was difficult to identify a couple of the elements that had colors that were similar. The Origin of Flame Colors; Contributors and Attributions; This page describes how to perform a flame test for a range of metal ions, and briefly discusses how the flame color arises. ... Be sure to include the questions listed in this lab with answers in the QUESTIONS section of your report. Place a small scoopful of each metallic solid in corresponding weighing dish. Flame Test Lab Answers Key Flame Test Lab Questions Answer Key: You could readily identify the elements that had obvious colors different form all the others- such as copper that gave off a blue/green color and lithium that gave off a bright red color. Some questions that you should address in your lab report include: Assessment Pre-Activity Assessment. Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. The color given off by the salt is the initial color observed, not the yellow-orange color produced by the burning wood. Label six weighing dishes. Explain how you know. 4. yellow-green. 4. orange. 3. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Repeat with other known compounds, using a clean splint each time.   Terms. 6. Known Metal cations: Calculated Energy Color Sample Wavelength Test Samples AICI 640 nM BaCl2 byellow CaCl2 6 70 neon-9reeh 35 nm blue-gceen CuCl2 KCI Gly pucple 355 LICI 729 nm pink-ed NaCI 2bues 740 nm SrCl2 Brighr red FeCl2 yellow Unknown Metal cations: B. Not all metal ions give flame colors. Start studying Flame Tests lab. Question: Identification Of Gases Hands-On Labs, Inc. 10. 6. Repeat steps 2-7 for the other two Flame Test Solutions using the remaining beakers and watch glasses 9. Data . 2. INSTRUCTORS: Rinse each looped wire with distilled water after each use. 5. While it's a useful qualitative analysis test—and a lot of fun to perform—it can't be used to identify all metals because not all metal ions yield flame colors.
