Beer-Lambert law
Define Beer-Lambert Law
Beer-Lambert law state that for any material the sample path length and the sample’s concentration are directly proportional to the absorbance of the light.
What are the limitations of Beer-Lambert Law?
Various limitations of the Beer-Lambert law are,
- It only works for the diluted solution.
- It fails when the scattering of the light beam occurs.
- It only works with Monochromatic Electromagnetic Radiation.
Why does Beer-Lambert Law fail at higher concentrations?
Beer-Lambert law fails at higher concentrations because higher concentration changes the refractive index of the solution and at higher concentrations, the molecule of the concentration are very close to each other which decreases the absorptivity of the solution.
Who discovered the Beer-Lambert Law?
The base of Beer-Lambert law was provided by Pierre Bouger in 1729.
What is the Beer-Lambert law Equation used for?
Beer-Lambert law is used to relate the movement of light with the properties of the material in which it is travelling which is very helpful in spectrophotometry and other activities.
Why is Beer-Lambert Law important?
Beer’s law is one of the most important laws of science. It finds its uses in various fields such as Physics, Chemistry and Meteorology. The law helps us to measure the concentration of chemical solutions, measure the degradation of polymers and analyze oxidation reactions.
When does the Beer-Lambert Law fail?
Beer-Lambert law fails for the solution containing a higher solution i.e. the concentration greater than 10-2 M.
Beer Lambert Law
Beer-Lambert Law derivation describes the relationship between the attenuation of light through a substance with the properties of that substance. It asserts that the length of a sample route and the concentration of a solution are proportional to the light’s absorbance. This law is dependent on the properties of the solution in question. It elaborates on the linear relationship between the concentration and absorbance of a solution.
