Beer's Law

Project Summary

Determine the concentration of an unknown copper sulfate solution.

Experiment Objectives

  • Prepare and test the absorbance of five standard copper (II) sulfate solutions.
  • Calculate a standard curve from the test results of the standard solutions.
  • Test the absorbance of a copper (II) sulfate solution of unknown molar concentration.
  • Calculate the molar concentration of the unknown CuSO4 solution.
