Flame emission spectroscopy Flashcards
1
Q
How does flame emission spectroscopy work?
A
It works by heating a sample in a flame and as the sample is heated, the electrons will become excited and emit light.
2
Q
What is the device used in flame emission spectroscopy?
A
A spectroscope which can detect the individual wavelengths of light that are emitted to produce a line spectrum.
3
Q
What does the intensity of a line spectrum indicate?
A
The concentration of the ion in solution.
4
Q
What is the main advantage of flame emission spectroscopy?
A
It can be used to identify different ions in mixtures as the spectrum will show the lines for all the ions.
5
Q
What are the 3 main benefits of instrumental methods?
A
Very sensitive.
Very fast.
Very accurate.
