That is, the flame converts the metal ions into atoms. When a solution of sodium chloride is placed in a flame, for example, the solvent evaporates, leaving behind solid crystalline sodium chloride. This evaporation is then followed by the dissociation of the sodium chloride crystals into individual ground state atoms - a process that is termed atomization.
This page describes how to perform a flame test for a range of metal ions, and briefly discusses how the flame color arises. CuCl2 Hydrochloric acid Nitric acid Ethanol: 8. Copper II (cupric) chloride has the chemical formula CuCl2.
Flaming rainbows: Pretty, but dangerous | Science News …
The other ion — sulfur or chloride, for example — has an electrical charge that balances out the metal. This pairing creates a salt with no net electrical charge. The color in the burning salts comes from the energy contained in their electrons — the negatively charged …
Colors of Elements in a Flame - Magnesium Chloride | …
No color is imparted to the flame by magnesium chloride. This indies that neither magnesium nor chlorine has a characteristic flame color. A few tinges of yellow-orange sodium color appear as a consequence of traces of sodium impurity in the magnesium chloride solution.

In Part One, 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. In Part
You have a sample of CaCl2 which is heated. What part of …
2010/1/1· Volatile salts like calcium chloride are vaporized in a flame and the calcium is the cause of the color of the flame. Other metal salts that give quite strong colors in a flame are strontium for a deep red, sodium for a deep yellow, potassium for a purple color and copper for a green or blue color depending on the temperature of the flame.
2 Why does each metal produce a different color …
2) Why does each metal produce a different color? Different elements have different flame colors because their electrons have different allowed energy levels. When the atom is heated, some electrons are excited to a higher level. When an electron drops from one
What Different Colored Flames Mean – SurvivalKit
Table salt, or sodium chloride, produces a light orange color, and green flames can be produced by copper sulfate and boric acid. Blue flames are produced by butane as well as copper chloride. Finally, you can produce violet flames with a coination of potassium sulfate and potassium nitrate where a peach colored flame is produced by potassium chloride.
Lab: Flame Test Flashcards | Quizlet
When a salt of the metal is introduced into a Bunsen burner flame, the metallic ion produces characteristic color in the flame. Some metals and the colors they produce are: barium, yellow-green; calcium, red-orange; copper salts (except halides), emerald green; copper halides or other copper salts moistened with hydrochloric acid, blue-green; lithium, crimson; potassium, violet; sodium, yellow

This is the flame of the sodium atoms inside the salt (sodium chloride). The beautiful colors of fireworks are using the flame reaction. In general, red is a strontium compound, calcium compound, yellow is a sodium compound, green barium compound, cooper compounds, are used for blue, and other colors are created by mixing those.
Colored flames - MEL Chemistry
Scarlet flame – lithium chloride It’s worth noting that the flame’s color depends on the metal ion; the salt’s anion has practically no influence whatsoever. This characteristic of certain metals is also exploited to produce colored lights — in pyrotechnics, for instance.

It should be noted that sodium is present as an impurity in many if not most metal salts. Because sodium imparts an especially intense color to a flame, flashes of the sodium may be observed in nearly all solutions tested. Scientific Concepts: When an element is
Chemistry - Calcium - Tutorialspoint
If calcium comes in contact with air, it reacts swiftly and forms a gray-white coating of calcium nitride and calcium oxide. Most of the calcium salts are normally colorless. When calcium burnt, the color of its flame appears brick red (see the image given below).
Note: Due to the vivid and persistent colored flame produced by the sodium chloride, the flame color of sodium should be demonstrated last. When flame colors become less vivid and take on a yellowish tinge, it is time to dry them in an oven overnight.
Lab #7: Observing the Behavior of Electrons Background
