Learn how to use the PASCO Wireless Spectrometer and Spectrometry software to perform a Beer's Law analysis of the concentration of a colored solution. After calibration and selection of wavelength, we establish the relationship between the absorbance and concentration for standard solutions and then determine the concentration of an unknown.
