accurate,sensitive and rapid methods which are useful when the amount of sample is very small
describe the flame emission spectroscopy
instrumental method used for identifying metal ions in solution or measuring their concentration
Spectroscope measures the exact wavelength of the light emitted by a metal ion
That allows for definite identification - sometimes colours are difficult to distinguish
Concentrations are found by measuring the intensity of light emitted. The more intense light, the greater the concentration of the metal ion in a solution.
From the intensity vs concentration graph, you can read off a relevant concentration value at a given intensity.
