With all the journals, books, and other publications about chemical demonstrations, how do you actually find a description and a procedure for a demonstration that will effectively get across exactly the point you want to teach? Try Demo-Deck. Fred Juergens has collected in one rapidly accessible form descriptions of about 1400 chemical demonstrations to help you illustrate chemistry better. The database and search capabilities of HyperCard make this an easy-to-use and very valuable resource.
Frost diagrams, plots of free energy versus oxidation state, are useful tools for predicting whether oxidation-reduction reactions will occur. The diagram for a single element can be used to predict disproportionation reactions of unstable oxidation states as well as reactions between different oxidation states of the same element. For reactions between two different elements two diagrams must be overlaid as movable transparencies.
James Birk and Heidi Hocker have overcome this difficulty nicely by using the graphics capabilities of HyperCard. Each element can be selected from a periodic table by clicking with a mouse, its Frost diagram can be displayed, and diagrams for two elements can easily be compared, all quickly and easily.
In addition to Demo-Deck and Frost Diagrams, there is a note with part of the index to the Journal of Chemical Education as a text file, continuing the practice of publishing such files that was begun in our first Macintosh issue.
Hardware and Software Requirements
The programs in this issues require a Macintosh Plus, SE, Classic, SE/30, or any Mac II model. They have been tested using versions 6.02 and 6.03 of the Macintosh system software and ought to be compatible with any version 6.x system. For those who wish to use the software for class presentations a large monitor or overhead projection panel for the Macintosh will be needed. Several such panels and monitors are available (1).
