View notes - beers law lab report from chem 104b at arizona the determination of molar absorptivity using beer's law author: michelle abercrombie lab partners: morgan. The beer–lambert law, also known as beer's law, the lambert–beer law, or the beer–lambert–bouguer law relates the attenuation of light to the properties of the material through which the light is travelling the law is commonly applied to chemical analysis measurements and used in understanding attenuation in. Bellevue college | chem& 161 page - 1 - of 9 beer’s law: determining the concentration of a solution background color additives are used in foods for a variety of reasons sometimes they are used to compensate for the natural color.

Beer's law lab context the absorption of light by a substance in a solution can be described mathematically by the beer-lambert law (usually abbreviated to beer’s law) the more light that is absorbed by a solution, the more deeply colored the solution is in.
