LAB. S2: Spectrophotometric: Transcript

Determination of Indomethacin Salicylic Acid Mixture Objectives Scan an absorbance spectrum using the spectrophotometer Deduce the dependence of the absorption coefficient on the wavelength. Spectrophotometric techniques are used to measure the concentration of solutes in solution by measuring the amount of light that is absorbed by the solution in a cuvette placed in the spectrophotome 1 Lab 8.
