Beer's law is an ideal technique that works only in certain situations. A method for dealing with more complex conditions needs to be integrated into the analytical chemistry curriculum. For that reason, the capabilities and limitations of two common chemometric algorithms, classical least squares (CLS) and principal component regression (PCR),…

Describes the structure of an in-depth laboratory project chemical engineering. Provides modeling work to guide experimentation and experimental work on heat transfer analysis. Discusses the experimental results and evaluation of the project. (YP)

A laboratory experiment is presented for the upper-level undergraduate physical chemistry curriculum in which the ternary phase diagram of water, 1-propanol and n-heptane is measured using proton nuclear magnetic resonance (NMR) spectroscopy. The experiment builds upon basic concepts of NMR spectral analysis, typically taught in the undergraduate…

This is the final report of the evaluation of Project CAUSE, a three year project to improve the laboratory portions of undergraduate physics courses at North Texas State University. The report is divided into six sections. Included in the overview are goals and purposes, the instructional format, and the evaluation plan. Demographic profiles…

This experiment was designed to help students improve the critical thinking skills that are required to analyze and discuss the results of an organic chemistry experiment in an effective manner. The initial objective indicated in the prelab handout for this puzzle experiment was the synthesis of methyl 4-bromobenzoate using the Fischer…
