Introduction: The purpose of Experiment 28 was to find which of the three artificial sweeteners, Equal, Sweet ‘n’ Low, or Splenda, contains aspartame. In order to determine which of these sweeteners contained aspartame, each type was put in a test tube of water, mixed thoroughly, and poured into a spot plate and tested. Equal turned out to be the sweetener that contained aspartame. Then, the absorbance of the solution containing Equal was measured in order to find the amount of aspartame present in the Equal. Experimental Procedure: The procedure followed is what was given in the lab manual: Sprague, Alexander, Padolik & Steffel, Laboratory Experiments For First Year Chemistry, 6 th Edition. pp. 28-2 to 28-5. Data and Results: The final calculations of the measurements for this experiment can be found on the attached Report Sheets. Graphs of the stock solution, 5 mL aspartame solution, and Beer’s Law Plot are also attached labeled ‘Graph 1,’ ‘Graph 2,’ and ‘Graph 3,’ respectively. Discussion:
