WebA flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic flame emission spectrum (which may be affected by the presence of chloride ion).The color of flames in general also depends on temperature and oxygen fed; see flame color.
