Who discovered the Beer-Lambert law?
Pierre Bouger discovered the law in 1729.
What does the Beer’s Law state?
Beer’s Law or the Beer-Lambert Law states that the amount of energy absorbed or transmitted by a solution is proportional to the solution’s molar absorptivity and the concentration of solute.
What is the Beer-Lambert law equation used for?
The Beer-Lambert law relates the attenuation of light to the material’s properties through which the light is travelling. The law is applied to the analysis of a mixture by spectrophotometry without extensive pre-processing of the sample.
Why is Beer-Lambert law important?
Beer’s law is important in the field of physics, chemistry and meteorology. The law is used in chemistry to measure the concentration of chemical solutions, analyse oxidation, and measure polymer degradation. The law also explains the attenuation of radiation through the Earth’s atmosphere.
When does the Beer-Lambert law fail?
The law fails at high concentrations (>0.01M) due to electrostatic interactions between molecules in proximity.
