Chemistry Departments In Predominantly Black Institutions, James O. Wear, Nirmal K. Shastri
Chemistry Departments In Predominantly Black Institutions, James O. Wear, Nirmal K. Shastri
Journal of the Arkansas Academy of Science
Chemistry programs in 87 predominantly Black institutions were compared by questionnaire survey. Advanced undergraduate courses were offered for chemistry majors by 86% of these schools, but only 28% offered research and independent study for undergraduates. Although there were extremes, most of the faculty taught 15 to 18 contact hours and their median salaries were below the national median. Library support seemed adequate with 1 to 1.5% of the total library materials being chemistry books, texts and reference, and the libraries of most schools had holdings of 15 principal chemistry-related journals. More than 90% of the schools were well-equipped with laboratory …

Preparation Of O-Fluorobenzoic Acid. An Elementary Organic Laboratory Experiment, Frank L. Setliff
Journal of the Arkansas Academy of Science
An experiment designed for organic chemistry students at the sophomore level is presented. The experiment, which involves no special equipment and which employs only inexpensive reagents, demonstrates the conversion of anthranilic acid to o-fluorobenzoic acid via the modified Schiemann Reaction.

Apparatus For Dielectric Constant Measurements And Measurements For Water-Methanol Mixtures, James O. Wear
Apparatus For Dielectric Constant Measurements And Measurements For Water-Methanol Mixtures, James O. Wear
Journal of the Arkansas Academy of Science
A system for measuring dielectric constants has been constructed using a Sargent Oscillometer and an air bath for temperature control. The design and construction of the air bath as well as the temperature control achieved with it are described. The overall performance of the system including a computer program for forming the calculations is described. The system is one that requires calibration using two or more standard solvents and is good for both conducting and non-conducting liquids. Data are presented for water-methanol mixtures at 25 degrees with several points near pure methanol and also near pure water
