Factors That Influence Relative Acid Strength in Water: A Simple Model  Michael J. Moran
The pKa's of diverse aqueous acids HA correlate well with the sum of two gas-phase properties: the HA bond-dissociation enthalpy and the electron affinity of the A radical. It is suggested that rather than bond strength alone or bond polarity, the sum of the enthalpies of these two steps is a fairly good indicator of relative acidity.

Rotational Mobility in a Crystal Studied by Dielectric Relaxation Spectroscopy. An Experiment for the Physical Chemistry Laboratory  Madalena S. C. Dionísio, Hermínio P. Diogo, J. P. S. Farinha, and Joaquim J. Moura-Ramos
In this article we present a laboratory experiment for an undergraduate physical chemistry course. The purpose of this experiment is the study of molecular mobility in a crystal using the technique of dielectric relaxation spectroscopy. The experiment illustrates important physical chemistry concepts. The background of the experimental technique deals with the concepts of orientational and induced polarization and frequency-dependent relative permittivity (or dielectric constant). The kinetic concepts of temperature-dependent relaxation time, activation energy, and activation entropy are involved in the concept of molecular mobility.

This experiment features an investigative approach designed for the introductory science or engineering major and integrates concepts in the fields of chemistry, biology, and physics. Derived from faculty research interests, this novel experiment gives students the opportunity to draw conclusions from tests performed to illustrate the connection between molecular structure and macroscopic properties. The chemical synthesis of the compounds studied further enhances the connection between molecular structure and macroscopic physical properties. The results of two separate physical measurements, refractometry and absorption spectroscopy, are combined to calculate a microscopic, but very practical, property of chiral nematic liquidsthe pitch of the helix formed in the liquid crystalline phase.

Assessing the Effect of Web-Based Learning Tools on Student Understanding of Stoichiometry Using Knowledge Space Theory  Ramesh D. Arasasingham, Mare Taagepera, Frank Potter, Ingrid Martorell, and Stacy Lonjers
This paper reports a comparative study using knowledge space theory (KST) to assess the impact of a Web-based instructional software program on students' understanding of the concept of stoichiometry. The software program called Mastering Chemistry Web (MCWeb) allows students to practice problems that emphasize the development of molecular-level conceptualization and visualization, analytical reasoning, and proportional reasoning, as well as learning to recognize and relate different representations in chemistry. The experimental design compared students in two sections taught by the same instructor. One section used the MCWeb instructional software as homework (MCWeb group) while the other section used text-based homework (non-MCWeb group, control).

Simple Dynamic Models for Hydrogen Bonding Using Velcro-Polarized Molecular Models  Emeric Schultz
This article describes the use of models that dynamically illustrate the unique characteristics of weak intermolecular interactions, specifically hydrogen bonds. The models clearly demonstrate that H-bonds can break and reform while covalent bonds stay intact. The manner in which the models form and break H-bonds reflects the geometric and statistical manner in which H-bonding actually occurs and is not contrived. The use of these models addresses a significant area of student misconceptions. The construction of these molecular models is described.

Applying Chemical Potential and Partial Pressure Concepts To Understand the Spontaneous Mixing of Helium and Air in a Helium-Inflated Balloon  Jee-Yon Lee, Hee-Soo Yoo, Jong Sook Park, Kwang-Jin Hwang, and Jin Seog Kim
In developing this laboratory, our initial motivation for the analysis of gases in a balloon was to answer simple and basic questions, such as, Why does a helium-charged balloon left in the air always drop in a few days? Is leakage of helium the only cause of the drop? What is the composition of the gas in the balloon when it falls after deflation? Students were intrigued by these questions, too, as they analyzed the variation over time in the composition in a balloon inflated with helium. Using the concepts of partial pressure and chemical potential, the laboratory experiment described effectively investigates the diffusion process and the behavior of gas molecules for teaching these concepts in general and physical chemistry.

A Laser-Pointer-Based Spectrometer for Endpoint Detection of EDTA Titrations  Christopher E. Dahm, James W. Hall, and Brian E. Mattioni
A simple laser-pointer-based spectrometer has been developed for endpoint detection of EDTA titrations of magnesium and calcium. This spectrometer was built to decrease the uncertainty in determining the endpoint of titrations performed with a Calmagite indicator. With a photoresistor as the detector, and with the aid of a voltage-divider circuit, the quantity of light being absorbed can be followed with a simple pHvoltmeter. Students determine the endpoint by graphing the data and applying simple mathematics. BeerLambert studies with the spectrometer also show excellent agreement for a given set of solutions.

Using Knowledge Space Theory To Assess Student Understanding of Stoichiometry  Ramesh D. Arasasingham, Mare Taagepera, Frank Potter, and Stacy Lonjers
Using the concept of stoichiometry we examined the ability of beginning college chemistry students to make connections among the molecular, symbolic, and graphical representations of chemical phenomena, as well as to conceptualize, visualize, and solve numerical problems. Students took a test designed to follow conceptual development; we then analyzed student responses and the connectivities of their responses, or the cognitive organization of the material or thinking patterns, applying knowledge space theory (KST). The results reveal that the students' logical frameworks of conceptual understanding were very weak and lacked an integrated understanding of some of the fundamental aspects of chemical reactivity.

Introduction of Mass Spectrometry in a First-Semester General Chemistry Laboratory Course: Quantification of MTBE or DMSO in Water  Mike Solow
An experiment has been developed to introduce first-semester general chemistry students to mass spectrometry. Students analyze water samples contaminated with a known compound, either DMSO or MTBE. Students are asked to determine the concentration of the compound in the water. In performing this experiment, students should learn (i) how the mass of an atom or molecule is determined, (ii) the effect of the presence of different isotopes on molecular mass, (iii) the role of an internal standard, and (iv) how mass spectrometry is used in answering various scientific questions.

Mass Spectrometry for the Masses  Jared D. Persinger, Geoffrey C. Hoops, and Michael J. Samide
In this article, we describe an experiment for an introductory chemistry course that incorporates the use of mass spectrometry for sample analysis. Several different air samples are collected that represent various chemical processes, and the composition of the air sample is predicted on the basis of known chemical principles. A gas chromatograph-mass spectrometer is used to analyze these samples, and the relative quantities of nitrogen, oxygen, carbon dioxide, water, and argon are calculated. On the basis of the data, the hypothesized sample composition is validated.

Chemistry as General Education  Nivaldo J. Tro
I suggest that current non-major chemistry courses cover too much consumer chemistry and ignore some of the big contributions of chemistry to human knowledge.

Consequently, chemistry courses are often an ineffective and unpopular way to meet general education science requirements.

A Comment on Molecular Geometry   Frank J. Gomba
A method of determining the correct molecular geometry of simple molecules and ions with one central atom is proposed. While the usual method of determining the molecular geometry involves first drawing the Lewis structure, this method can be used without doing so. In fact, the Lewis structure need not be drawn at all. The Lewis structure may be drawn as the final step, with the geometry of the simple molecule or ion already established.
