What is the flame test the flame test is used to visually determine the identity of an unknown metal of an ionic salt based on the characteristic color the salt turns the flame of a bunsen burner. Peripheral interest for the analysis of major flame processes known blue color with flames burning with excess fuel in the free atmosphere this blue radiation and the ultraviolet oh bands are observed mainly in the emission from the outer zone of the flame.
Flame tests help miners, geologists miners use the test for analysis of samples, particularly when prospecting the flame emits its own color, and that can interfere with some spectrum colors, notably orange. Chemistry 201 qualitative analysis introduction general comments: it is always a good idea to use as few chemicals as possible in many cases, the color of the observed flame can be correlated to the chemical identity of the cations and anions in the solution (see fig b71, in silberberg.
