Answer» The Beer-Lambert law states that the quantity of light absorbed by a substance dissolved in a fully transmitting solvent is directly proportional to the concentration of the substance and the path length of the light through the solution. Because Beer's law states this, it means we can both calculate the concentration of a solution by using the absorbancies, or plot a graph of various concentrations, align them to their correct absorbencies, and use a colorimeter to find the concentration of an unknown solution The law states that: A(λ) =e(λ)lc.The proportionality constante(λ) is called the absorptivity of the substance at the wavelengthλ.e(λ) is called the molar absorptivity if the concentration is measured in moles/liter. The absorbance is inversely proportional to the transmittence of the solution |
