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 … Meer weergeven 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, … Meer weergeven The flame test is relatively quick and simple to perform and can be carried out with the basic equipment found in most chemistry … Meer weergeven • Flame Test - Coloring Fire - Pictures of Several Flame Tests, Includes Instructions • WebMineral.com - Flame Coloration by Element Meer weergeven • Bead test • Spark testing • Colored fire • Emission spectrum Meer weergeven WebColors in a flame test result from what characteristic of electrons? a.
