The Beer-Lambert law is an empirical law that states that the absorbance of a solution is directly proportional to the concentration of the absorbing species in the solution.
The unit of absorbance in the Beer-Lambert law is the decibel (dB).
The Beer-Lambert law is used in spectroscopy to measure the concentration of a species in a solution by measuring the absorbance of the solution at a particular wavelength.
The concentration of a species in a solution can be calculated using the Beer-Lambert law by measuring the absorbance of the solution at a particular wavelength and then using the equation A = εcl, where A is the absorbance, ε is the molar absorptivity, c is the concentration, and l is the path length.
The Beer-Lambert law is a linear equation, meaning that the absorbance is directly proportional to the concentration of the absorbing species in the solution.
