Question

State Beer-Lambert's law?

Answer 1

The Beer-Lambert law is a mathematical relationship that describes the absorption of light by a solution. It states that the absorbance of a sample is directly proportional to the concentration of the absorbing species and the path length of the light through the sample.

Step-by-step explanation:

The Beer-Lambert law, also known as the Beer-Lambert-Bouguer law, is a mathematical relationship that describes the absorption of light by a solution. It states that the absorbance of a sample is directly proportional to the concentration of the absorbing species and the path length of the light through the sample. The equation commonly used to represent Beer-Lambert's law is:

Absorbance (A) = molar absorptivity (ε) * concentration (c) * path length (l)

Where ε is the absorption coefficient, c is the concentration of the absorbing species, and l is the path length of the light.

Answer 2

Beer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c: A α b · c. The proportionality constant is sometimes given the symbol a, giving Beer's law an alphabetic look: A = a · b · c.
