Discussion
Which one of the following can be estimated by Flame Photometer ?
Answer: A
A flame photometer can estimate sodium and potassium, option A. The instrument measures the intensity of the light that an element gives out when it is heated in a flame, and the alkali metals sodium and potassium are excited easily at low temperature, which makes the method simple and sensitive for them.
Cadmium and cobalt (option B), chlorine and bromine (option C) and mercury and arsenic (option D) are not excited enough in the flame of this instrument to give a dependable signal, and are measured by atomic absorption, ion chromatography or other methods.
