ChemEd X Subscribers enjoy access to a large collection of videos and the associated still images.
The ChemEd X video collection includes modernized versions of the Chemistry Comes Alive! video collection. In addition to this award-winning collection, contributors continue to create some very interesting video.
Note: We are currently updating the ChemEd X video collection. While we do, playing ChemEd X video on Internet Explorer has issues. We recommend that you use Google Chrome or Firefox until these issues are resolved. We apologize for the inconvenience and thank you for your patience.
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.

A knife is placed on a large sodium chloride crystal parallel to a cleavage plane. When the knife is tapped, the crystal breaks cleanly, creating two smaller crystals. When one of these crystals is tapped with the knife at an angle, it shatters, breaking along a cleavage plane rather than parallel to the knife blade.
The three alkali metals, lithium, sodium, and potassium, reacting with water are shown together in order to readily compare their relative reativity.
Acidic aqueous solutions containing dichromate and iodide ions are mixed with no reaction. The addition of a solution of iron(II) ion induces the rapid formation of brown triiodide ion.
