Precipitation reactions are used to produce iron(III) oxide (Fe2O3 called hematite) and mixed iron(II)/iron(III) oxide (Fe3O4 called magnetite). The particles in the slurry of hematite are not attracted to a magnet, but the particles in the slurry of magnetite are.

Mixing solid iodine and cyclohexene shows little reaction but mixing iodine and α-pinene produces a very vigorous exothermic reaction and sublimation of solid iodine to dense iodine vapor.

This video is one part of a video experiment, which is one experiment of six that can be used to engage in thinking about "Like Dissolves Like" solubility. This series of six experiments involves permutations of mixing three liquids, using a powder to provide color so that the layers can be readily seen. Each of the six experiments is presented in three parts.
