Calculating concentration using the Beer

The absorbance (A) is a unitless number because Io I I o I is unitless.For reasons to do with the form of the Beer-Lambert Law (below), the relationship between A (the absorbance) and the two intensities is given by: A = log_ {10}\frac {I_0} {I} A = log10 I I 0. It is done by using the standard solutions of the known solute concentration that has to be determined. Beer Lambert’s law states that “when a beam of monochromatic light is passed through a solution of an absorbing substance, then the rate of decrease in intensity of radiation with the thickness of absorbing solution is directly proportional to intensity as well as to the concentration of the solution. This law establishes a relationship between the absorption of light by a substance and its physical-chemical properties, providing a basis for determining the concentration of an absorbing .
