A reality show about a college course--a chemistry class no less? That's what "ChemLab Boot Camp" is. The 14-part series of short videos is being released one episode at a time on the online learning site of the Massachusetts Institute of Technology. The novel show follows a diverse group of 14 freshmen as they struggle to master the…

Although various methods are used to study solution chemistry, relationships between them are generally not self-evident, and the theory and procedure underlying each technique are frequently learned and memorized separately. Therefore, all of these methods are classified within a unified framework that clearly demonstrates relationships and…

Describes a method by which teachers can either produce their own silver of "technical" quality or recycle silver chloride residues to recover the silver for similar reuse. Procedures used are outlined and economics of the method are discussed. (JN)

A previous part (Analytical Chemistry; v57 n9 p1057A) discussed the theoretical aspects of diode ultraviolet-visual (UV-VIS) spectroscopy. This part describes the applications of diode arrays in analytical chemistry, also considering spectroelectrochemistry, high performance liquid chromatography (HPLC), HPLC data processing, stopped flow, and…

Reviews various spectroscopic techniques currently used to analyze real physical surfaces that bound two actual phases. Problems inherent in analyzing these surfaces and possible approaches that may be taken are considered. (JN)

Describes an experiment to demonstrate Boyle's law that provides pressure measurements in a familiar unit (psi) and makes no assumptions concerning atmospheric pressure. Items needed include bathroom scales and a 60-ml syringe, castor oil, disposable 3-ml syringe and needle, modeling clay, pliers, and a wooden block. Commercial devices use a…

Two demonstrations are described which are suitable for introductory chemistry classes. The first involves the precipitation of silver, and the second is a demonstration of the relationship between rate constants and equilibrium constants using water and beakers. (BB)

Describes experiments in which students determine the ground state ionization constant (GSIC) by analyzing the absorption spectra of 2-naphthol in acidic, basic, and buffered solutions. Information on the ground and excited state ionization constants and on the kinetics of the excited state deprotonation-protonation reaction is included. (JN)

Job's method of continuous variations is a commonly used procedure for determining the composition of complexes in solution. Presents: (1) a review of the method; (2) theory of a new procedure for measuring Job's plots; and (3) an undergraduate experiment using the new method. (JN)

The 38th Annual Summer Symposium on Analytical Chemistry (June 18-20, 1985) focused on the surface characterization of catalytic and electronic materials. Highlights of the symposium are provided, including presentations that considered lasers and microscopy. (JN)

Discusses two surface techniques: X-ray photoelectron spectroscopy (ESCA) and Auger electron spectroscopy (AES). Focuses on fundamental aspects of each technique, important features of instrumentation, and some examples of how ESCA and AES have been applied to analytical surface problems. (JN)

Background information, procedures, equipment, and results for two experiments are presented. The first involves the measurement of the mass-average and degree of coiling of polystyrene and is interpreted by the full mathematical theory of light scattering. The second is the study of transitions in gelatin. (JN)

Describes a physical chemistry experiment which allows such concepts as kinetics, catalysis, isotope shifts, coupling constants, and the use of nuclear magnetic resonance (NMR) for quantitative work to be covered in the same exercise. Background information, experimental procedures used, and typical results obtained are included. (JN)

Background information, procedures used, and typical results obtained are provided for an experiment in which students prepare and study the characteristics of a "slime." A list of general, inorganic, and polymer chemistry concepts fostered in the experiment is included. (JN)

Discusses materials needed, procedures used, and typical results obtained for an experiment involving a dry attack of ores with pyrosulfate flux. The experiment has been carried out by about 150 students a year with a demonstrator-to-student ratio of about 1:15 with no serious accidents. (JN)
