Hampton University, Hampton, VA. A flame test is a complex phenomenon that is not fully explained. In simple words, when a solution of metal salts, e.g., an aqueous solution of metal chlorides is injected into a flame, some of the metal ions may gain electrons and become neutral metal atoms.
How are elements identified by using a flame test? A metal salt is a compound of a metal and a nonmetal. When dissolved in water, the metal and nonmetal atoms separate into charged particles called ions. As the metal ion is heated by the flame, the electrons gain energy and move to outer orbitals.
To do a flame test with each metal salt get a film of the solution of a salt inside the loop and bring it into the flame. Try the edge, the top, and the center of the flame. Repeat the dip into the salt solution as often as necessary to see the flame test color. Be sure not to over-heat the loop.Oct 14, 2019 · The flame test is one of the most commonly used analytical processes in chemistry.
