Lithium chloride flame test colour
Did you know?
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 emit light when being in flame. The solvent of the solution evaporates first, leaving finely divided solid particles which move to the hottest region of the flame where gaseous atoms and ions are produced through the dissociation of molecules. Here electrons are … WebYour Safer Source for Science. 1-800-452-1261 M–F, 7:30 AM–5:00 PM CST
