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. The solvent of the solution evaporates first, leaving finely divided solid particles which move to the hottest region of the flame where gaseous atoms and ions are produced through the dissociation of molecules. Here electrons are … WebFlame tests (Li, Na, K, Ba, Sr, Cu) Theory The characteristic colours given off when salts of certain metals are heated in the flame of a Bunsen burner are noted. The colours obtained can then be used to identify the metals present in unknown compounds. Procedure NB : Wear your safety glasses. Crush a little of the salt to be tested with a pestle
