Principal of Lambert Beers law

Question

Accepted Answer

Lambert Beers law states that the absorbance of a solution is directly proportional to the concentration of the absorbing species.

The law is used to determine the concentration of a substance in a solution by measuring its absorbance.
It assumes that the absorbing species is uniformly distributed throughout the solution.
The law is often used in spectroscopy and colorimetry.
The equation for the law is A = εlc, where A is absorbance, ε is the molar absorptivity, l is the path length of the sample, and c is the concentration of the absorbing species.
The law can be used to determine the concentration of a substance in a mixture by measuring the absorbance at different wavelengths and using a calibration curve.
