CHEM 446 Physical Chemistry Laboratory Spring 2012 Textbook: There is no course text. Some experiments were originally designed around experiments in books like D. P. Shoemaker, C. W. Garland, J. W. Nibler, Experiments in Physical Chemistry , 6th Edition, McGraw-Hill, New York, 1996, or A. M. Halpern, Experimental Physical Chemistry, A Laboratory Textbook , 2 nd Edition, Prentice-Hall, Englewood Cliffs, New Jersey, 1997; or J. M. White, Physical Chemistry Laboratory Experiments , Prentice-Hall, Englewood Cliffs, New Jersey, 1975. Our experiments are not quite identical to the experiments in those books, but you should use them as references. Where appropriate, the corresponding pages in these books are indicated as a reference for you. Sequence Experiments are done in rotation. Each student performs the following laboratory experiments. A schedule of laboratory experiments is posted in the laboratory and also on the Web: ( http://www.udel.edu/pchem/C446/c446.htm ). In addition, each student must do the experiment on the statistical treatment of data. Laboratory Experiments Dipole Moment of Polar Molecules in Solution Determining the “Size” of a Molecule from Viscosity Conductance of Solutions (Determining the Equilibrium Constant of Acetic Acid) Experimental and Calculated Vibration-rotation Spectra of HCl, DCl, and CO Surface Tension of Pure Liquids Kinetics of Reduction of Methylene Blue Information on each experiment at the University of Delaware is available as a downloadable PDF file at the course Web site. Preparation for the Laboratory Prepare for each experiment carefully. Reading the theory and experimental procedure thoroughly before walking into the laboratory. Outside of class time, during the week BEFORE you are to start an experiment, you and your laboratory partner should meet to discuss the experiment. Summarize in your laboratory notebook any important points about the experiment (things like the number of values of a variable you plan to investigate, including specific numbers if possible, the possible problems you might encounter, the possible results you might expect, and possible alternate

experimental studies). The object of this exercise is to think about HOW to do the experiment BEFORE you come to laboratory. The notebook should be clear on what you intend to do and how you are going to do that. Six experiments are being done simultaneously. At this level of activity the instructor cannot describe each experiment at the beginning of the laboratory period. If you are found not to be prepared, you will be asked to leave the laboratory. Only when you have demonstrated knowledge of the experiment will you be allowed to return. General Information
