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 Passive Sampler for Determination of Nitrogen Dioxide in Ambient Air Dan Xiao, Lianzhi Lin, Hongyan Yuan, Martin M. F. Choi, and Winghong Chan
This article describes the use of a passive sampler for detecting and collecting nitrogen dioxide, NO2, in ambient air. This device is based on microporous PTFE membranes that allow air samples to diffuse through and subsequently react with an absorbing reagent solution. The absorbance value of this reagent is proportional to the NO2 concentration in ambient air. It has been successfully applied to determine the NO2 concentrations in various sampling sites.

Valence, Covalence, Hypervalence, Oxidation State, and Coordination Number Derek W. Smith
It is argued that the terms valence, covalence, hypervalence, oxidation state, and coordination number are often confused and misused in the literature. It is recommended that use of the term valence, and its associated terminology, should be restricted to simple molecular main group substances and to some oxoacids and derivatives, but avoided in both main group and transition element coordination chemistry.

Our Everyday Cup of Coffee: The Chemistry behind Its Magic Marino Petracco
Coffee beverages are so popular all over the world that there is hardly any need to describe them. But underlying this seemingly commonplace beverage there is a whole realm worth serious scientific study. The complexity of the raw seed matrix, made even more intricate when roasted, requires a deep understanding of its chemical nature. While coffee is not consumed for nutritional purposes, it is appreciated for its taste appeal along with its stimulating effects on mental and physical activity. The attention to quality is of paramount importance to both of these aspects to supply the customers with a pleasant and wholesome product.

We generalized the question into: Why does soap performance depend on the hardness of the water used? A sequence of experiments was carried out to compare the performance of soap in soft and hard water and to illustrate the water-softening action of EDTA and zeolites.

Measuring Viscoelastic Deformation with an Optical Mouse T. W. Ng
A simple demonstration of viscoelasticity can be carried out by attaching a weight to a polymer film and watching it extend over time. For accurate and quantifiable data on the deformation, an electronic displacement sensor should be incorporated. Most of such sensors are expensive. Here, an optical mouse was demonstrated to provide accurate data at low cost. The experiment was also devised in a manner to allow students to learn about viscoelastic deformation experientially.

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.

Consumer Views on Chemical Additives: Are They Natural or Synthetic? A Non-Laboratory-Based Project A. S. Cotterill, D. N. John, and Y. S. Teh
Results of a study demonstrate that consumers are not well informed about identifying natural products but do recognize names to which they have been exposed. Consumers also appreciate that natural compounds can come from a variety of sources and can be synthesized, and that a natural substance is not necessarily good for you or better than a synthetic substance. However, despite this knowledge, consumers do prefer products that contain natural or natural-sounding additives.

The Fizz Keeper, a Case Study in Chemical Education, Equilibrium, and Kinetics Reed Howald
The chemistry of the loss of carbonation from carbonated beverages on storage is considered. Increasing the pressure of CO2(g) will restore carbonation, but an increase in pressure adding air should not affect the equilibria. It can and does, however, affect the kinetics-the rate at which a new equilibrium is established. Thus the Fizz Keeper is effective for storage of resealed pop containers for hours, but not for periods of weeks or months.
