Colorimetry
In this technique , the concentration of compound is determined by measuring the intensity of color.
Colorimeter
They are simple instrument which measure the intensity of transmitted light through color solution
Beer’s law
When a parallel beam of monochromatic light is passed through a solution, the absorbance (A) of the solution is directly proportional to concentration (C) of the substance in solution
A = KC
K is a proportionality constant
Lambert’s Law
When a parallel beam of monochromatic light is passed through a solution, the absorbance (A) of the solution is directly proportional to length of the light path (l)
A=Kl
