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 fed; see flame color. WebToday, I will give you an overview of this common experiment that you might do in your chemistry class. To understand the flame test, you need to know about the electromagnetic spectrum. Light has a dual nature; it is made up of both particles and waves. This was proved by Thomas Young’s double-slit experiment that he performed in 1801.

WebAtomic absorption spectroscopy uses light in the ultraviolet-visible range. For Pb analysis, a thin beam of light is passed through the flame containing the analyte. The beam contains light at 283.3 nm. The light is absorbed by Pb atoms as excitation of electrons from the Pb ground state to the first energy level occurs.
