Frost Diagrams is a HyperCard stack that provides an easily used format for making redox reaction predictions for one or two elements by comparing slopes of the lines connecting two oxidation states. Comparisons are simplified by copying the Frost diagram for one element to a new card, then overlaying the diagram for the second element using Paint tools, so that the second diagram remains transparent and movable. The two diagrams can be aligned in any way desired, so that any two half reactions can be compared. In addition, some common reduction half-reactions are collected on a single card with their lower energies aligned, thus making it possible to overlay all these half reaction diagrams at once on the diagram of any element. In this way predictions of which common reduction half-reactions can cause a desired oxidation half reaction to occur are greatly simplified. Frost Diagrams contains diagrams for 98 elements, each of which can be selected by clicking on that element's symbol in a periodic table.
Hardware and Software Requirements
Frost Diagrams requires a Macintosh Plus, SE, Classic, SE/30, or any Mac II model. The program has 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).
