A thin-layer fuel cell is described that is simple and easy to set up and is particularly useful for teaching and classroom demonstrations. The cell is both an electrolyzer and a fuel cell and operates using a thin layer of electrolyte with a thickness of ~127 µm and a volume of ~ 40 µL. As an elect...

Many students in general and advanced chemistry courses have difficulty understanding differences in solubility by inspecting changing values of the solubility product constants for sparingly soluble salts. In this demonstration, the concepts involved in understanding the solubility of sparingly sol...

The ability to use series expansions effectively is one of the important skills for students in quantum chemistry courses. This Mathcad template enables students to practice this skill using the Fourier series. Students start with the definition of orthonormal functions and then move on to the funda...

The use of equations of state to evaluate volumetric properties is straightforward for students, at least when the ideal gas equation of state is used. The application of a more complicated equation of state, for example a cubic equation, is a little more difficult, especially for the determination ...

Our featured molecules for this month come from the paper by André J. Simpson, Azadeh Shirzadi, Timothy E. Burrow, Andrew P. Dicks, Brent Lefebvre, and Tricia Corrin (1). In the article, the authors describe the use of NMR to identify and quantify a number of components in the energy drink Red Bull,...

The article “Glowmatography”, by Thomas S. Kuntzleman, Anna E. Comfort, and Bruce W. Baldwin, is the source of this month’s Featured Molecules (1). Three molecules from the paper have been added to the collection and several rhodamine derivatives were featured in the November 2007 column (2).
The...

This month our featured molecules come from two sources, the paper by Marina Canepa Kittredge, Kevin W. Kittredge, Melissa S. Sokol, Arlyne M. Sarquis, and Laura M. Sennet on the stability of benzoyl peroxide (1) and the paper by Graciela Mahler, Danilo Davyt, Sandra Gordon, Marcelo Incerti, Ivana N...

This month’s issue of the Journal includes several papers discussing interesting molecules that fall into the broad category of natural products, and four of these papers serve as the source for our featured molecules this time around. Addison Ault weaves an interesting tale of the search for the tr...

In keeping with the 2008 National Chemistry Week theme of “Having a Ball with Chemistry”, the Featured Molecules this month are a number of monomers and their associated polymers taken from a paper by Sandy Van Natta and John P. Williams on polymers used in making equipment for a variety of high-imp...

Deirdre Bell-Oudry presents a variation on an old theme in her paper on using an indirect EDTA titration for sulfate analysis (1). EDTA and (often loosely) related species are this month’s Featured Molecules.
EDTA is a hexaprotic acid (H6Y2+) having the pKa...

A series of demonstrations is described that elucidate the operation of commercial fog machines by using common laboratory equipment and supplies. The formation of fogs, or "mixing clouds", is discussed in terms of the phase diagram for water and other chemical principles. The demonstrations can be ...
