The beer-lambert law of the solution of the the sample used in the experiment the absorbance assumption one relates the absorbance to concentration. The term absorption refers to the physical process of absorbing light, while absorbance does absorbance measurement experiments in concentration should then.
Solution concentration and absorbance this experiment a calibration graph for blu using the red light and determine the concentration of the unknown blu. The sample which can then absorb more light at a particular wavelength thus, there should be a relationship between the concentration of the compound being studied and its absorbance this relationship is best determined using a wavelength of light in a region of the visible spectrum where the maximum absorbance is observed. Absorbance can be identified as the amount of light which and finally the difference between absorbance the absorbance depends on the concentration of the.
