Flame color of mg
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.

WebThe red lithium flame leads to lithium's use in flares and pyrotechnics Copper compounds glow green or blue-green in a flame. Calcium compounds glow orange in a flame. Sodium compounds glow yellow in a flame. A pyrotechnic colorant is a chemical compound which causes a flame to burn with a particular color. WebThe absorption of energy from the flame excites electrons from their ground energy level to excited energy levels, which when they transition to lower energy levels again, lead to the release of photons in the visible region thereby giving a color to the flame. The wavelength corresponding to sodium is 589 nm which provides it a yellow color.
