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.
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.
Observe the color of the flame. Allow only half of the wood splint to burn. Extinguish the wooden splint by placing it in your rinse beaker. Record your observations for the flame color by the metal chloride in the Data Table. Repeat steps 7-10 for the other metal

The flame test is preformed by burning a metal salt using a flammable liquid. Each chemical (in this case metal ion) gives off a characteristic color (seen here as changes in colors of the flames) when the electrons fall back down from their excited state and emit light at certain wavelengths (colors).

Flame Test Lab Report found in a compound. And in order to detect the presence of metals in a compound, flame test is done. The result of the flame test is based on each element’s characteristic which is emission spectrum. Flame test involves placing a sample of an element or compound in a non-luminous flame and observing the resulting color of the flame.
