A kit is described for use in automation of routine chemical research procedures. The kit uses sensors to evaluate the state of the system, actuators which modify the adjustable parameters, and an organ of decision which uses the information from the sensors. (BB)

Summarizes a theoretical approach using nonbonding MO's and perturbation theory to correlate properties of saturated hydrocarbons. Discussion is limited to correctly predicted using this method. Suggests calculations can be carried out quickly in organic chemistry. (Author/SA)

Discusses a student exercise which requires the optimizing of the charring and atomization temperatures by producing a plot of absorbance versus temperature for each temperature parameter. Notes that although the graphite furnace atomic absorption spectroscopy technique has widespread industrial use, there are no published, structured experiments…

Describes two examples where synthetic salt-base mixtures are used in a microscale organic laboratory program as a simple and quick procedure for carrying out Wittig reactions. Both experimental procedures are outlined and discussed. (TW)

Notes the careful observation of chemical reactivity phenomena has been and should be an important part of the general chemistry laboratory curriculum. Stresses reduction of experimental scale will help to ensure, in times of rampant chemophobia, that it remains so. Provides several examples of the methodology. (MVL)

Presents a halogen substitution of an alkane using a compartmentalized Petri dish or Conway dish on an overhead projector. Provides methodology and several modifications for different reactions. Uses hexane, methyl orange, bromine, and silver nitrate. (MVL)

Compares the revised Blue Bottle formulation to the classical Blue Bottle. Indicates that the revised formulation gives a somewhat bluer solution, but initially slower reduction when compared to the classical formulation. (Author/KHR)

After a short historical background, sources of information on reactive chemical hazards are discussed, along with reasons why these sources are not being tapped, particularly in academic laboratories, and some underlying principles. (BB)

Describes the adaptation of thermite (aluminum with metal oxides) reactions from whole-class demonstrations to student-run micro-reactions. Lists detailed directions and possible variations of the experiment. (WRM)

Data from this study suggest that evaluations of long-term accumulations of students' laboratory analyses should be standard procedure to detect deviations from the accepted true assays. Efforts are recommended to determine the cause of the error and the implications or grading procedures reconsidered. (Author/MA)

Describes a convenient method of preparing chlorine water by mixing hydrochloric acid with sodium hypochlorite. (DKM)

Presents a chemistry activity that introduces students to one type of chemical bond by developing the integer operation concept of zero pairs. Leads to an activity of combining drops of 0.3 molar solutions to form six different colored precipitates from five solutions. (ASK)

This inexpensive, effective chemiluminescence demonstration requires minimal preparation. It is based on the oxidation of oxalyl chloride by hydrogen peroxide in the presence of an appropriate fluorescent sensitizer. The reaction mechanism is not completely understood. (BB)

Smaller amounts of materials are used in organic chemistry experiments as a means of improving air quality in the laboratory. Outlines benefits from this approach and describes two representative experiments in detail. These experiments are the Cannizzaro reaction and preparation of an aromatic nitrile. (JN)

Presents an activity on chemical changes and experimentation with testing the roles of various reactants in accomplishing the changes. (Author/KHR)
