Students are learning too many facts, and not enough emphasis is being placed on observational skills. An activity is suggested for college students which shows how observations are made and problems formulated from them. (BB)

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)

General chemistry courses and texts seemed to be geared to students who are going to be chemistry majors. This may relate to the trend of declining interest and knowledge of chemistry. A course is proposed which concentrates only on the most essential facts and fundamental laws and theories. (BB)

Contains a short history of the development of industrial chemistry. (BB)

This freshman chemistry lab relates stoichiometric problems to real situations. It requires students to measure the Fe impurity in reagent grade calcium chloride. (BB)

A discussion is presented on the role of secondary teachers in public schools, followed by a sequence for teaching oxidation-reduction in secondary school chemistry courses. (BB)

Reported here is a convenient alternative for determining the enantiomeric purity of student resolved alpha-phenylethyl amine using a chiral lanthanide shift reagent. (BB)

This experiment graphically demonstrates a change in the sign of the P-C-H coupling constant between trivalent phosphorus and tetravalent phosphorus. (BB)

This reaction can form the basis of a laboratory experiment for students who have mastered basic spectroscopy. The structure of the product can be assigned from four reasonable possibilities on the basis of the nmr spectrum. (BB)

This experiment provides an excellent practical application of computer-controlled spectrometers. (BB)

Various approaches to the standardization of pH meters are compared and the limitations of each are pointed out. (BB)

Two experiments are presented which help to illustrate a modular approach to electrochemical instrument design, but which are readily understandable to students with a limited electronics background. The experiments are coulometric titration and controlled potential coulometry.

An apparatus is described for storing laboratory glassware in freshman organic chemistry laboratories. The glassware is mounted on pegboard using hardware gripper clips, and the pegboard is fitted in a slot down one side of the storage cupboard. (BB)

Inexpensive, low-density polyethylene tubing has physical characteristics about midway between glass and rubber. For many laboratory uses it may be superior to both. (BB)

Presented is an inspection form developed for use by college students to perform laboratory safety inspections. The form lists and classifies chemicals and is used to locate such physical facilities as: fume hoods, eye-wash fountains, deluge showers, and flammable storage cabinets. (BT)
