Describes an experiment which allows students to observe the four oxidation states of vanadium obtained in aqueous solution. (SL)

Describes a simple chemistry laboratory experiment which allows students to calculate thermodynamic values. (SL)

Describes a laboratory kinetic experiment which demonstrates the important phenomenon of general catalysis by bases and/or acids. (SL)

Describes a chemical experiment which illustrates the Beckman rearrangement and ring opening reactions. (SL)

Compares the preparation and decomposition of potassium dibromoiodate and of phenyl iodine dichloride in a flexible experiment which accustoms the student to handle halogens, to test for halogens in mixtures, and to appreciate the difference between thermodynamic and kinetic control of reactions. (Author/MA)

Reports an experiment demonstrating the existence of the oscillatory phenomenon in the manganese +2 catalyzed reaction between citric acid and potassium bromate. (SL)

Describes an advanced physical or inorganic chemistry experiment in determining the rate law of chemical reactions which demonstrates unusual behavior of k-obs. (SL)

Describes an experiment designed to provide the opportunity for studying some of the parameters affecting the stability of Vitamin C in various environments, and to acquaint the student with an experimental procedure for studying simple reaction kinetics and the calculations of specific rate constants. (Author/JR)

Presents an organic chemistry experiment consisting of a two step reaction sequence involving the Grignard synthesis of an alcohol followed by its oxidation to ketone. (SL)

Describes a physical chemistry experiment investigating the vapor-liquid equilibrium in a heterogeneous system. (SL)

Describes a simple method for purifying catalase for the study of proteins. Procedures are systematically and diagramatically presented. Also identifies polyacrylamide gel electrophoresis, kinetic studies, and apparent molecular weight determination as possible techniques to be used in studying proteins. (ML)

Describes a laboratory method suitable for senior high school classes for investigating possible mechanisms of catalytic function. The Harcourt-Essen reaction is used to demonstrate a catalytic process that can be investigated quantitatively by standard kinetic methods. (JR)

Proposes that the psychological problem of students expecting a particular result in an organic chemistry laboratory and, therefore, working in an unthinking manner be attacked by assigning experiments that give students unexpected results. Gives four examples of such experiments with strategies for teaching them. (CW)

Describes two demonstration experiments for the chemistry laboratory: (1) Thermodynamic vs kinetic control and (2) Acid-Catalyzed Hydrolysis of Starch. (MA)
