The Flame Test The flame test is a qualitative test used in chemistry to help determine the identity or possible identity of a metal or metalloid ion found in an ionic compound. If the compound is placed in the flame of a gas burner, there may be a characteristic color given off that is visible to the naked eye. Safety: Always use good safety techniques. Wear chemical splash approved goggles. Wear a chemical apron. Practice the flame test under the supervision of a chemistry teacher. To perform the flame test: The classic technique is to use a clean wire loop made out of platinum or nickel-chromium (nichrome) wire, dip the loop into the powder or solution to be tested, and then placed into the hottest portion of a flame.
The test involves introducing a sample of the element or compound to a hot, non-luminous flame, and observing the color of the flame that results. The idea of the test is that sample atoms evaporate and since they are hot, they emit light when being in flame.
