Proposes a simple and general method whereby the lattice energies of lanthanide(II) and (IV) compounds are derived directly from those found experimentally for the corresponding lanthanide(III) compounds. The method is applicable to all lanthanide halides and oxides and involves calculations which can be easily and quickly performed by students.…

Discusses the structure and function of the liver protein cytochrome P-450, an important catalyst for a variety of detoxification reactions. Diagnostic substracts for this heme-containing monooxygenase, synthetic modes of the active site, and oxidations with synthetic metalloporphyrins are the major topic areas considered. (JN)

The topic of ionic radius is generally given scant treatment in modern textbooks. Therefore, this article reviews some historical work and illustrates some of the applications of ionic radii in the teaching of inorganic chemistry. (JN)

Seven recent inorganic chemistry textbooks are examined and compared with each other and with textbooks from the 1960s. Findings show several different and contrasting trends in the topics emphasized, allowing teachers to select a textbook most aligned with their course content or philosophy. (JN)

Draws a distinction between the terms "heat and work" and "energy" in terms of the teaching of thermodynamics. Gives examples using enthalpy and constant pressure processes, free energy and spontaneity, and free energy and available mechanical energy. Concludes that there is no thermodynamic role for the terms "heat"…

Background information, procedures used, and typical results obtained are provided for a simple homogeneous precipitation preparation of chromium(II) acetate. (JN)

Background information (including relevant chemical reactions), procedures used, and results obtained are provided for the synthesis and characterization of a macrobicyclic complex. The synthesis can be completed within two to three hours and is inexpensive and safe. Suggestions for further experiments are included. (JN)

Discusses the properties of surface-conducting glass and the chemical nature of surface-conducting stannic (tin) oxide. Also provides the procedures necessary for the preparation of surface-conducting stannic oxide films on glass substrates. The experiment is suitable for the advanced inorganic chemistry laboratory. (JN)

Biomimetic chemistry is concerned with the synthesis of small, molecular weight molecules which mimic the properties of metal-containing sites within certain biologically significant species. A series of experiments for an advanced undergraduate laboratory is described as a way to introduce this area into the chemistry curriculum. (JN)

Oxidation kinetics in metals and the role defects play in diffusion-controlled reactions are discussed as background for a junior/senior-level experiment in the physical or inorganic chemistry laboratory. Procedures used and typical data obtained are provided for the experiment. (JN)

Presents a mathematical and abstract approach to teaching the second law of thermodynamics in physical chemistry that is not used in any undergraduate physical chemistry text to date. (CW)

Several interesting and important examples of kinetic stability and kinetic control in organic systems are discussed. Audiovisual aids, lecture demonstrations, and laboratory activities that can be used to convey the material in a clear and stimulating fashion are also described. (JN)

Describes a procedure for the qualitative analysis of aluminum subgroup cations designed to avoid failure to obtain lead or barium chromate precipitates or failure to report aluminum hydroxide when present (due to staining). Provides a flow chart and step-by-step explanation for the new procedure, indicating significantly improved student results.…

Background information (including optical properties of inorganic materials) and procedures are provided for an experiment which introduces students to preparation of a doped semiconductor; phosphorescence; gettering procedures; reducing atmospheres; and use of a high-temperature furnace with associated thermocouples, temperature controllers, and…

Incorporates the combined effects of ionic strength and ion association to show how calculations involving ionic equilibria are carried out. Examines the variability of reduction potential data for two aqueous redox systems. Provides several examples. (MVL)
