A: It''s important to test the flame before adding any compounds to compare the original flame color to the color of compounds (i.e. Borax, table salt, etc.). 2) List the colors observed in this lab from highest to lowest frequency.
Flame Tests - Drs.Cavanaugh
Flame Tests Just as a fingerprint is unique to each person, the color of light emitted after excitation of an element is different for each element. When a metallic element’s electrons absorb energy, by heating for example, the electron is said to become “excited”.

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.

Q & A: Flame test: ion or anion? | Department of …
If you use a pure metal powder and observe a color spectrum, it is clearly due to the metal atoms as there is nothing else. The question that you are asking comes into play when you use a metallic salt, which upon heating disassociates into metal ions and nonmetalic anion atoms or groups.

Do It Yourself | Causes of Color
You can test sodium carbonate and calcium carbonate to prove to yourself that it is the metallic part (the ion) of the compound producing the color. Hence, sodium carbonate will produce a yellow flame and calcium carbonate (chalk or limestone) will produce a red-orange flame.

What Colors are Produced by Burning different Chemicals …
Calcium salts burn orange. Salts are made up of a metal and a nonmetal. In each case, it is the metal that provides the color when the salt is burned. That is why both copper chloride and copper sulfate burn blue. Other metallic salts produce some outstanding
Why are chlorides used in flame test? | Socratic
2016/6/21· There are two reasons why chlorides are used in flame tests. > 1. Metal chlorides are usually more volatile than other salts. More of the salt will be converted to vapour in the flame and therefore give a brighter colour. 2. Chlorine atoms do not emit energy in the visible region. In the flame test, electrons in both the metal atoms and the chlorine atoms are excited to higher energy levels
