WebMay 16, 2015 · 13 Flame tests are a common way of identifying trace amounts of alkali metals (and to a lesser extent alkaline earth metals) in mixtures. Certain salts of B a, S r … 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 … WebMay 28, 2024 · If a pure metal is heated up in a flame, we see it giving the flame a characteristic color, e.g. N a burns yellow. If a salt, e.g. N a C l or N a X 2 S O X 4, is heated up, resulting color to a greater degree still is that of the pure metal. Although the color does change depending on the anion, this effect is usually not much pronounced. how long are drywall anchors
