Resumen de An Introductory Experience for Physical Chemistry:: Victor Meyer Revisited
An introductory experience for experimental physical chemistry is presented on JCE Online. The experiment incorporates a class determination of random error along with the determination of the molecular weight of a volatile liquid using a modified Victor Meyer procedure. Rapid data collection allows the class to amass a sizable data set for analysis. The experimental presentation contains a detailed write-up on the handling of random error and its propagation in subsequent calculations. A slight simplification of the Guedens et al. (J. Chem. Educ. 1993, 70, 776-779 and 838-841) treatment of statistical experimental error is presented at a student level. It can also be used as a trial experiment for report writing. Since it is based on the ideal gas law, it is consistent, in most cases, with the lecture material in a physical chemistry lecture-laboratory sequence.
