Uses paper chromatography with food dyes to provide a simple and inexpensive basis for teaching chromatography. Provides experimental methodology and tabled results. Includes a solvent system comparison (Rf) for seven dyes and twenty-two solvents. (MVL)

Examines the thermal decomposition of sodium bicarbonate to sodium carbonate. Encourages students to predict the end products and to use the stoichiometric results to determine if their predictions are correct. (MVL)

Describes an undergraduate chemistry experiment in which the concentration of chloride, fluoride, or bromide ions can be quantitatively determined by titrating with mercury (II) ions. (MLH)

Describes an experimental procedure for the analysis of common cations in solution for an introductory analytical chemistry course. (SL)

Describes an experiment suitable for an instrumental analysis or quantitative analysis course. (BB)

Describes an experiment for general chemistry students for analyzing bathroom cleansers. (SL)

Describes an experiment to distinguish aldehydes from ketones utilizing a recently introduced reagent. (SL)

Describes a three period project type laboratory experiment designed to maintain student interest. (SL)

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

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

Presents an experiment for determining the pH of shampoo. (SL)

Describes an experiment to introduce students to qualitative and quantitative aspects of neutron activation analysis. (SL)

Presents an analytical or inorganic chemistry laboratory experiment in preparing nickel macrocyclic complex. (SL)

Discusses an addition to an apparatus which allows the effect of temperature on a paramagnetic compound to be measured, therefore demonstrating the Curie-Weiss law. The experiment can be used as a demonstration or student experiment to stimulate discussion of magnetic susceptibility and ligand field trips. (Author/JN)

This experiment demonstrates the reduction of inorganic sulfate to sulfide in the pore water of estuarine muds. Procedures involve the incubation of mud samples for varying amounts of time followed by gravimetric determination. (Author/SA)
