explain how you can use a spectroscope to identify the components of solutions containing several different metal ions?
Answers
Spectroscopy is used to identify the lights properties over the specific portion of light spectrum.
So, when a solution is placed in the spectroscope, it identified it's components by the measure light and separate the different colours of light and thus also separate the different components of the solution in to individuals one.
This was different metal ions can also be identified.
Hope it helps you in your study.
A spectrophotometer or a spectroscope is used to measure absorbance values by recording the spectra values.
Light is allowed to pass through a monochromator where only the desired wave length or a very narrow range of wavelengths passes through. From here, the light passes through the sample solution and then to a phototube wherein the conversion of light energy to an electrical current takes place. This change is then registered on a meter, which is recorded as the absorbance values.
A sample solution that contains colored substance absorbs visible light and it allows determination of the concentration of the colored substances in the solution.
If there are many colored substances in the solution, the colored components could possibly interact in a way the total light-absorbing property of the solution mixture is not just a simple sum of the individual components.
