Flame Tests lab. In this lab students will make qualitative observations of flame color, a property of metals, to identify unknown metals in salt compounds. This is caused by the flame exciting the electrons of the metal element in a compound. Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. They are worried about some abandoned, rusted barrels of chemicals that. Flame TestFlame Test LabLab. Flame Test Chemistry Lab Answers 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. Pre-Lab Questions. Photons were produced when the energy passed through the atoms and the difference in the atoms (#’s of protons, neutrons and electrons) determines the wavelengths of the photons produced. Purpose The purpose of this lab was to reinforce the examination of wavelengths in photons discharged from atoms as they move from high energy to low energy, atomic emmision.

The production of specific photons by specific elements is very useful to astronomers because they can look at the wavelengths of the photons that are produced by stars to determine the elements that compose that star. Chemical Concepts Share. Key Concepts: Terms in this set (22) Purpose. Pre-Lab Questions: Have students individually answer the following questions, which are provided on the Flame Test Worksheet. These colors come from the In this laboratory activity, the characteristic color of light emitted for calcium, copper, lithium, potassium, sodium, and strontium will be observed. The responding variable was the color of the flame. Each of the compounds was similar in that they were all metal reacted with chloride. You will measure wavelengths of each sample and then use the speed of light equation to Flaming Pickles: Watch the Flaming Pickles demonstration and answer the following questions?

Flame Test Lab Answer Key Selecting a complicated answering program workforce to operate in your case can change to be a really good approach to extend purchaser care gratification. The Flame Test lab has been perfected by Robert Bunsen, who created the Bunsen burner. It has been found that metallic ions exhibit characteristic colors when vaporized in the burner flame. Flame Test Pre-Lab discussion and Questions Chemists began studying colored flames in the 18th century and soon used the term “flame tests” to distinguish between some elements. Flame Test Lab Your company has been contracted by Julius and Annette Benetti. The color of the light emitted from a sample can be used as a means of identifying the elements present. Use flame tests to identify a metal or metallic salt by the color that it produces when it is put into a flame. Identify unknown metallic Ions by means of its flame test. The purpose of the flame test lab is to observe the characteristics colors produced by certain metallic Ions when vaporized in a flame. It was important to use a different wood splint for each test because the wood splint was contaminated by the prior element which would have effected the color of the element being tested. On your way home from the fireworks show you drive by many establishments vying for your attention with their glowing signs, many of which are bright red.
