BEERS LAWS
BEERS LAWS Education,Law,Writing Beers law is also known as Beer-Lambert law. Beers law is the equation that relates attenuation of the light to the properties of a particular material. The beers law states that the chemical concentration is directly proportional to solution absorbed. This relationship is used to decide the chemical species concentration in a specified solution with the use a spectrophotometer. Beer law is written as A=?bc. Where A is the absorbance, ? is the molar absorptivity, b is the path length of a sample and c is a concentration of a compound solution. When calculating absorbance, you have to consider the following assumptions. The first assumption is that absorbance is quite directly proportional to a length of a path of a particular sample which can be expressed as A ?c(1.1) A?c and the second assumption is that the absorbance is said to be directly proportional to concentration of a particular sample it is expressed as A?1(1.3)(1.3)A?1.
