Webunexcited ground-state atoms in the flame. Because the wavelength of the light beam is characteristic of only the metal being determined, the light energy absorbed by the flame is a measure of the concentration of that metal in the sample. This principle is the basis of atomic absorption spectrophotometry. 3.0 DEFINITIONS WebAug 14, 2024 · The color is muted when sodium salts are placed in a blue flame, such as a Bunsen burner or alcohol lamp. Be aware, sodium yellow overwhelms other colors. If …
