Flame colouration of lithium
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. For other metals, there are usually other easy methods which are more reliable - but the ... WebFlame Spectrum. Blue. Azure. Cu Cl 2.

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 oxygen … 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. However, the range of elements positively detectable under these conditions is small, as the test relies on the See more • Bead test • Spark testing • Colored fire • Emission spectrum See more • Flame Test - Coloring Fire - Pictures of Several Flame Tests, Includes Instructions • WebMineral.com - Flame Coloration by Element See more WebWe would like to show you a description here but the site won’t allow us.
