WebThese flames can be used to produce atomic emmision spectra of the elements combusted. Using known values of emmision spectra, one can perform a flame test on un unknown substance, gather an emmision spectrum from it, and determine which elements are in the unknown substance. WebFlame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got.

The flame test is relatively quick and simple to perform and can be carried out with the basic equipment found in most chemistry laboratories. However, the range of elements positively detectable under these conditions is small, as the test relies on the subjective experience of the experimenter rather … See more A 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 … See more 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 … See more • Flame Test - Coloring Fire - Pictures of Several Flame Tests, Includes Instructions • WebMineral.com - Flame Coloration by Element See more • Bead test • Spark testing • Colored fire • Emission spectrum • Photoelectric flame photometer See more WebFlame Spectrum.
