Abstract In this experiment‚ the absorbance of KMnO4 was measured by spectrophotometric method to determine the molar concentration and the molar extinction coefficient of KMnO4. In part 1‚ in order to determine the maximum absorbance wavelength of KMnO4‚ we measured the absorbance of the sample solution which contains KMnO4 at the wavelengths between 330nm and 660nm‚ and plotted the λ and A points; the λmax was 530nm. In part 2‚ the effect of concentration on the absorbance was examined. We prepared

Spectrophotometric Methods: The Determination of Iron The goal of this laboratory experiment was the quantitative spectrophotometric determination of Fe (II) by using a calibration plot‚ which obeyed the Beer-Lambert Law. In order to determine the Fe (II) concentration‚ a series of solutions of known concentrations were made. The solutions were analyzed by the Ocean Optics spectrophotometer in order to determine their absorbance. The concentration of the unknown Fe (II) was determined by the “eye-ball”
