CHEM 121L Section 7Nov 8, 2017 Absorbance Spectroscopy and Beer’s LawIn this procedure, the various absorbance levels of different concentrations of a solution were measured using aphotospectrometer. This was done in order to determine the concentration of an unknown solution. This lab provedto be successful in finding an approximate concentration of the solution, 0.024 M.IntroductionThe study of the electrons in atoms is very important because it is essential in predicting how those atoms will behave. However, it is difficult to do so because of the incredibly small scale of the electrons themselves. For this reason, we use an indirect probe - the photon - to study the behavior of electrons. In this lab, this is studied by measuring the absorbance spectrum of CupricIons in water. These measurements are then used to determine the concentration of a cupric sulfate solute in a water solvent.Procedure●First the amount of CuSO4 needed to prep a 50mL 0.1m solution was found to be 1.248 grams.●After finding the amount needed and prepping the solution, a spectrometer cuvette was filled with the solution.
