Answer to Question #2026 in Inorganic Chemistry for vinay

Question #2026
State Beer-Lambert law. Explain its application.
Expert's answer
Beer-Lambert law states that the optical absorbance of a chromophore in a transparent solvent varies linearly with both the sample cell pathlength and the chromophore concentration.

/cgi-bin/mimetex.cgi?A_%7B%5Clambda%7D%20=%20%5Cvarepsilon_%7B%5Clambda%7D%20b%20c,
where ελ = molar absorptivity or extinction coefficient of the chromophore at wavelength λ (the optical density of a 1-cm thick sample of a 1 M solution). ελ is a property of the material and the solvent. b = sample pathlength in centimeters. c = concentration of the compound in the sample, in molarity (mol L-1).
An absorbance of 0 at some wavelength means that no light of that particular wavelength has been absorbed. An absorbance of 1 happens when 90% of the light at that wavelength has been absorbed.
