Method:

  • Gathered Equipment and Materials. Set up data collection system, linked it to the spectrometer, and turned on the computer. 
  • Cleaned test tubes and cuvettes. Added 10 mL of each solution to each test tube, the 6th of which received water. Filled each cuvette 2/3rds of the way with the solutions, and the 6th with water.
  • Inserted each cuvette one at a time. Recorded absorbance of each solution, one at a time, saving each before moving on to the next. Linked to computer, and generated graph of absorption spectra for all solutions. Printed graph. Saved Data.
  • Disposed of solutions in designated containers. Cleaned all test tubes and cuvettes, before returning all equipment to its point of origin.
