Proving the Beer Lambert Law Abstract: For this experiment we tested the absorbency of copper sulphate in different concentrations to prove the Beer Lambert Law. Introduction: This Law: Provides an experimental link between the absorbance properties of a solution of a given compound and its concentration. This is normally expressed as . A = Absorbance measured = Absorptivity C = Molar concentration L = Length of cuvette Equipment: • Gilson pipette • Eppendorf tubes • Copper sulphate
