WebMay 16, 2015 · 13 Flame tests are a common way of identifying trace amounts of alkali metals (and to a lesser extent alkaline earth metals) in mixtures. Certain salts of B a, S r are also used in fireworks for their ability to impart a colour to the flame. Although predominant among s block elements this behaviour is also seen in other elements like C … WebFlame Test: The flame test is an analytical method used to identify a metal that is not known in a sample. The flame test produces a characteristic colour when the salt is being heated on a Bunsen burner. For different elements, the flame colour is different. The flame colours for common ions, such as sodium and potassium, are yellow and lilac. shucks glasgow restaurant
