Weak Acid Titration Report Author: Spencer Stewart Co-Investigator: Nicole Dibona Kara Lamack Kayla Ward Supervisor: Xiaoyan Tu Sponsoring Organization: Chemistry 104B Section 101 Date Experiment was Performed: 14 February 2008 Date Report was Submitted: 28 February 2008 Abstract By using Beer’s law and a spectrometer to measure changes in concentration during a reaction it was determined that the rate constant was roughly doubled when the concentration of bleach used in the reaction was quadrupled. The average k value for the experiment performed during the first week was 584.8/sec*M and 1181/sec*M for the second week.

Introduction The objective of this experiment was to have students prepare a strong base solution of NaOH and standardize it, determine the moles of weak acid from a titration, determine Ka values from the titration data, and then use this information to determine the identity of the unknown weak acids. Experimental The procedures for this experiment can be found in the Fundamental Techniques of Chemistry , 6 th edition, author Seven L. Brown, Department of Chemistry, University of Arizona. Materials and Reagents All materials and reagents for this experiment were provided by the University of Arizona. Techniques All procedures and techniques for this experiment were provided in detail in the lab manual, Fundamental Techniques of Chemistry . Results
