Flame test for lithium
WebFlame Tests Flame Coloration by Element Table of Flame Colorations and Emission Spectra This table of flame coloration is modified from the book "Determinative Mineralogy and Blowpipe Analysis" by Brush & Penfield, 1906. The colors are best observed by heating the sample on a loop of platinum wire moistened with HCl. 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 presence of chloride ion). The color of flames in general also depends on temperature and … 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 results. The idea of the test is that sample atoms evaporate and since they are hot, they … See more The flame test is relatively quick and simple to perform and can be carried out with the basic equipment found in most chemistry laboratories.
