Electrochemical Polishing of Silverware: A Demonstration of Voltaic and Galvanic Cells  Michelle M. Ivey and Eugene T. Smith
Using a battery and a graphite electrode, an electrolytic cell is constructed to generate a layer of tarnish on silverware. Students then determine that the tarnish can be removed by electrochemically converting it back to silver using aluminum foil and baking soda.

The Different Periodic Tables of Dmitrii Mendeleev  Michael Laing
Between 1869 and 1905 the Russian chemist Dmitrii Mendeleev published several tables with different arrangements of the chemical elements. Four of these are compared with periodic tables by Russian scientists from 1934 and 1969.

Measurement of the Isotopic Ratio of 10B/11B in NaBH4 by 1H NMR  Murray Zanger and Guillermo Moyna
A simple and remarkably accurate method for estimating the isotopic ratio between 10B and 11B through the use of 1H nuclear magnetic resonance (NMR) spectroscopy is presented. The experiment relies on the splitting caused by 10B (I = 3) and 11B (I = 3/2) on the 1H signal of a proton directly bound to boron, a phenomenon readily observed on an aqueous sample of NaBH4. In combination with a brief lecture or prelaboratory presentation, this laboratory can serve to introduce students to magnetic properties as well as theoretical and experimental aspects of NMR spectroscopy as early as the freshman-level chemistry.

Boron Clusters  William F. Coleman
The review paper by Russell N. Grimes on boron clusters reminds us both of the past impact that these interesting structures have had on the development of our understanding of cluster chemistry and on the future development of what one might refer to as "post-fullerene" clusters.

Ammonia Can Crush  Ed Vitz
When a 12-oz aluminum soft drink can filled with ammonia or hydrogen chloride gas is inverted and dipped into water, the rapidly dissolving gas evacuates the can and the can is crushed before water can be drawn into it. This demonstrates, among other things, the remarkable strength of hydrogen bonds.

Microscale Thermite Reactions  Francisco J. Arnáiz, Rafael Aguado, and Susana Arnáiz
The reaction of aluminum with the oxides of a variety of elements illustrates exothermic reactions that require a high activation energy. It is also an appropriate experiment with regard to the discussion of Ellingham diagrams. When drama is not the main objective, conducting these reactions at microscale level offers numerous advantages over the usual scale.
