WebFlame Test Lab Report. 1017 Words5 Pages. Introduction: In the flame test, the electrons of the flame become excited through the application of heat whilst at the same time reacting with the gas (emitted from the reaction of a metal carbonate and hydrochloric acid). This ‘excitement’ causes electrons to move from their current energy level ... WebAug 16, 2024 · You can use a flame test to help identify the composition of a sample. The test is used to identify metal ions (and certain other ions) based on the characteristic emission spectrum of the elements. The test is performed by dipping a wire or wooden splint into a sample solution or coating it with the powdered metal salt.
