FLAME TEST LAB When metal salts (ionic compounds) are heated in a Bunsen burner flame, the metal gives off a characteristic color For example, sodium makes the flame turn bright orange – this is the same orange color made by sodium street lamps and many fireworks In this lab you will be given six unknown samples of metal Flame Test Part 1
Flame Tests, Atomic Spectra and Appliions Activity
In this activity, wooden splints dipped in solutions of metal salts are heated using a Bunsen burner, producing different colored flames. By comparing the color given off by an unknown with the known metal salts, the identity of the metal salt can be determined. Flame Tests Activity (As an option, this could be a demo rather than a student

Where do all of the colors come from? In this activity, you will investigate the colors of light produced by metal salts. Just as a fingerprint is unique to each person, the color of light emitted by metals heated in a flame is unique to each metal. A flame test is a procedure used to test for the presence of certain metals in chemical compounds.
flame tests - chemguide
Sodium''s familiar bright orange-yellow flame colour results from promoted electrons falling back from the 3p 1 level to their normal 3s 1 level. The exact sizes of the possible jumps in energy terms vary from one metal to another. That means that each different metal will have a different pattern of spectral lines, and so a different flame colour.
Essay about Easy flame - 365 Words
Flame test: AIM: To determine which part of the salt is responsible for the characteristics in the flame.HYPOTHESIS: If we introduce a metal salt in the blue flame of the Bunsen burner, then the colour given off by the flame is due to the metal part of the salt. METHOD: (1) With a heat proof mat under the Bunsen burner, turn the gas on and light up the Bunsen burner with matches.
Why does a salt compound give off light (or a colored
The flame test is a chemical test that helps scientists identify different metals. During the test, a metal is exposed to a flame, and the color is noted.
Cool Fire - Rice University
A distinct spot of a different color on the surface is good evidence for the reaction. Write net ionic equations for each reaction . Arrange Ag, Cu, Pb and Zn in order of their increasing strength as reducing agents. If a metal A reacts with a ion of another metal B, metal A is a stronger reducing agent, more reactive than metal B.
What gives fireworks their colors? — Quartz
Jul 03, 2017· The pellets that generate color are tiny balls of chemical salt. These salts are different metal and nonmetal compounds bonded together by a superstrong hold between the positively-charged metal
Colored Flames – Science On
Jun 21, 2018· Metal chlorides tend to be readily available, and the chlorine can help strengthen the color. So my introducing the metal salt to the flame, a demonstrator can turn the fire a different color. This isn’t only a cool display- scientists use flame tests to qualitatively determine whether an element in present in the sample.
How to Use the flame test to determine an unknown metal
The flame test is used to visually determine the identity of an unknown metal of an ionic salt based on the characteristic color the salt turns the flame of a bunsen burner. Want to master Microsoft Excel and take your work-from-home job prospects to the next level?
Rocket Propellant Types | ScienceBlogs
May 21, 2009· Beyond the thrust curve, there is an art to the color of the propellant (achieved through special metal salt additives). My 9 ft tall Sledgehammer, lifting off on a M1550 Redline motor from
Ask an Expert: Rainbow Fire -- Hypothesis???
Hmm, so the question to be evaluated is "During a flame test, why do different metals emit different colors of light when burned?" or "During a flame test, what characteristics about the metal salts causes the color to change?" I think these are good questions! But I am not sure how I would receive the answers when doing this experiment.
Teaching Guide: Scaling a flashy demonstration
The classic flame test demonstration will be used to illustrate how a demonstration can be scaled up or down as dictated by such limitations. For small classrooms, Q-tips® dipped in aqueous solutions of metal salts can be placed in a candle, burner, or alcohol lamp flame [3, 4, 6]; for medium sized rooms methanol solutions of the
The Flame Test - Science Olympiad
If there is no distinct color, then it is ready for use. If you have more loops, use a different loop for each test. The clean loop is dipped in either a powder or solution of an ionic (metal) salt. The loop is then placed in blue part of the gas burner flame. Note the color of the flame and match the color to the list at the end of this document.
Lamp and candle with a colored flame - LESESNE JOHN SHERMAN
Jun 22, 2004· The metal salts in the candle composition cause the flame to burn with a characteristic color that is different from a color the flame would burn in the absence of the metal salts. In one eodiment, the solvent may be a glycol (e.g., propylene glycol) and the hardener may be a long chain fatty acid (e.g., stearic acid).
