Social ScienceProject 2: Food Dye Spectroscopy What method will you use to assess the absorbance-concentration relationship? (The most obvious method is to see if there is a linear relationship between the absorbance and the concentration. What methods do you know that might reveal such a linear relationship?)
Expert Answer
There is a relationship between concentration and absorbance. This relationship is expressed by the Lambert-Beer law, which is more commonly known as Beer's law. This law states that the absorbance of a light absorbing material is proportional to its concentration in solution.
Some colors of light are blocked by the molecules and Absorbed, while others pass through and are transmitted.
It is also possible to relate absorbance at a given wavelength to the concentration of the absorbing material present in a solution. This direct relationship between absorbance and concentration for a solution is known as the Beer-Lambert Law, or more commonly Beer’s Law. You can use Beer’s Law to test several samples of a solution, of known molar concentrations,...
