A.8.6 Find the  concentration of a solution via calibration curve (Beer-Lambert law) IB Chemistry HL
Simple: 1) Find the most absorbed wavelength in your sample using a spectrometer. 2) Accurately measure the colour of multiple concentrations of your sample. 3) Plot a graph of concentration against concentration -- tah dah you have a calibration curve based on the Beer-Lambert Law. Now you can find the unknown concentrations of other samples. Tricky: Absorbance = log Io/ I = elc where Io= intensity of incoming light I=intensity of outgoing light e= constant for the substance l =path length of light through the substance c=concentration of substance It's in the data book!
