The Use of Conjugate Charts in Transfer Reactions: A Unified Approach Michael I. Allnutt Redox reactions are discussed in terms of the relative strengths of the oxidant, the reductant, and their conjugates; a conjugate chart is a convenient and useful way of doing this. A similar chart for acids and bases that can be applied in the same manner is proposed. Allnutt, Michael I. J. Chem. Educ. 2007, 84, 1659.

Slide Projector Corrosion Cell Silvia Tejada, Estela Guevara, and Esperanza Olivares The process of corrosion can be demonstrated in a slide projector, since the cell is in the shape of a slide, or on the stage of an overhead projector by setting up a simple galvanic cell. Corrosion occurs as the result of a galvanic cell reaction, in which the corroding metal acts as the anode. Several simple demonstrations relating to corrosion are described here.
