Improving Conceptions in Analytical Chemistry: ci Vi = cf Vf  Margarita Rodríguez-López and Arnaldo Carrasquillo Jr.
A common misconception related to analytical chemistry, which may be generalized as the failure to recognize and to account analytically for changes in substance density, is discussed. A cautionary example is made through the use of mass-based units of composition during volumetric dilution. The correct application of the volumetric dilution equation ci Vi = cf Vf is discussed. A quantitative description of the systematic error introduced by incorrect use of the volumetric dilution equation is also specified.

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).

A Note on Dalton's Law: Myths, Facts, and Implementation  Ronald W. Missen and William R. Smith
The treatment of Dalton's law for gas mixtures commonly includes the improper designation "Dalton's law of partial pressures", rather than the correct "Dalton's law of additivity of (pure component) pressures". It also identifies the pure component pressure as the partial pressure, although these are only numerically equal for a mixture of ideal gases. The situation is clarified by examination of an appropriate statement of the law and definitions, eventually in operational form with reference to mixtures of nonideal gases.

Cross-Proportions: A Conceptual Method for Developing Quantitative Problem-Solving Skills  Elzbieta Cook and Robert L. Cook
This paper focuses attention on the cross-proportion (C-P) method of mathematical problem solving, which was once widely used in chemical calculations. We propose that this method regain currency as an alternative to the dimensional analysis (DA) method, particularly in lower-level chemistry courses. In recent years, the DA method has emerged as the only problem solving mechanism offered to high-school and general chemistry students in contemporary textbooks, replacing more conceptual methods, C-P included.

Equilibrium Constants and Water Activity  David Keeports
General chemistry instructors are faced with a dilemma when introducing the topic of equilibrium constants: These constants are correctly written in terms of activities, yet activity is a complex topic better treated rigorously in a physical chemistry course than superficially in a general chemistry course. Thus, to introduce equilibrium calculations, it is necessary to use approximate forms for equilibrium constants. However, I find that some commonly used textbooks provide incorrect arguments leading to approximate equilibrium constants for aqueous reactions.

Let's Drive "Driving Force" Out of Chemistry  Norman C. Craig

The usefulness of the competition of ?H versus ?S in discussing chemical change is also questioned. Entropy analyseswhich consider the contributions to the total change in entropyare advocated.

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.

Heat and Temperature Conductivity of Baths. Author Reply  Erik Joling
I appreciate the suggestions made by Bruno Lunelli to improve the usefulness of the microscale heater we described. However, for use in secondary schools sand works fine. In spite of the better properties I would not recommend the use of silicone oil with relatively inexperienced 16-year-old pupils since it can be a bit messy. But that is an argument of classroom management, not of chemistry.

It is designed for use in an introductory chemistry course. The students will learn about acidbase interactions and examine how a buffer system composed of a weak acid and its conjugate base can neutralize large quantities of strong acid while resisting drastic change in the pH of the system. Students will also analyze experimentally the various components of the most commonly occurring natural buffer system.

Water in the Atmosphere  Joel M. Kauffman
None of eight college-level general chemistry texts gave a mean value for water in the atmosphere, despite its being the third most prevalent constituent at about 1.5% by mass as vapor and about 2% if clouds and ice crystals are included. The importance of water as a greenhouse gas was omitted or marginalized by five of the eight texts. An infrared spectrum of humid air was determined to demonstrate that water vapor, because of its higher concentration, was more absorptive than carbon dioxide. The cooling effect of clouds, or other influences on the Earth's albedo, were not mentioned in most of the texts. These pervasive errors should be corrected in new or future editions of textbooks.

Identifying Bottled Water: A Problem-Solving Exercise in Chemical Identification  Richard L. Myers
Students are challenged to identify water samples using the known chemical analyses of bottled waters.

A periodic table of any size can be transformed into a stereo model which is called the Periodic Building of the Elements (PBE).

The whole model is obtained by simply combining these two submodels together.
