Measuring the Density of a Sugar Solution  Karen I. Peterson
This experiment addresses the concept of equipment calibration for reducing systematic error. Students prepare and measure the densities of sucrose solutions with simple glassware that has been calibrated using the density of water. By careful work, students can determine the density to within 0.5%. allowing accuracy to be a major component of the final grade.

Kinetic Analysis of Amylase Using Quantitative Benedict's and Iodine Starch Reagents  Beverly Cochran, Deborah Lunday, and Frank Miskevich
This laboratory emphasizes that enzymes mediate the conversion of a substrate into a product and that either the concentration of product or reactant may be used to follow the course of a reaction. It does so by using an inexpensive scanner and open-source image analysis software to quantify amylase activity through the breakdown of starch and the appearance of glucose.

Structures for the ABO(H) Blood Group: Which Textbook Is Correct?  John M. Risley
Six textbooks and two Internet sites show different structures for the A, B, and O(H) antigens of the ABO(H) blood group, but none of them are correct. This article emphasizes the correct molecular structures because it is important to distinguish between those carbohydrates that make up the antigens and those that are not part of the antigenic structures.

Making Usable, Quality Opaque or Transparent Soap  Suzanne T. Mabrouk
First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching.

A Greener Approach for Measuring Colligative Properties  Sean M. McCarthy and Scott W. Gordon-Wylie
As a first step towards the greening of instructional laboratories, we present a new greener version of a laboratory procedure designed to measure colligative properties. The greener procedure substitutes the nontoxic, noncarcinogenic compounds stearic, myristic, lauric, and palmitic acids for the less benign aromatic compounds p-dichlorobenzene, benzil, biphenyl, naphthalene, and nitrotoluene. Achieving educational goals without the concomitant generation of chlorinated and aromatic wastes is shown here to be both possible and practical.

This experiment is easily done in a two-hour lab period, except for the evaporation of lipid extracts to dryness, which proceeds overnight and is weighed by the students the following day

Chocolate: A Marvelous Natural Product of Chemistry  Ginger Tannenbaum
This article is a survey of chocolate from tree to table. After a brief introduction to the history of chocolate and how and where it is grown, the manufacturing process is examined, and the chemistry is explored. A bit of the jargon used in the industry is mentioned. Cocoa butter is a significant ingredient in chocolate, and an investigation of it introduces triglycerides, fatty acids, polymorphic behavior, and molecular packing of the fats in chocolate and how they affect the tempering process. There is a brief discussion of chocolate's non-Newtonian behavior and the resulting challenges presented in the manufacturing process.
