Cover: Microscale Precipitation Chemistry

Microscale and green chemistry methods have a major impact on the general chemistry laboratory experience. Precipitation reactions, once investigated in test tubes, can be performed with as little as two crystals and a 10-drop puddle of water, as described by Bob Worley, Eric M. Villa, Jess M. Gunn, and Bruce Mattson in . The photo sequence on the cover shows crystals of silver nitrate and potassium iodide, both carried by moistened toothpicks, and brought to the puddle where they can be seen to shrink in size as they dissolve. The ions migrate across the puddle and within 15 s a precipitate of silver iodide starts to form at the interface of the two local solutions. The precipitate continues to develop along the interface.

On ChemEd X: Chad Husting has previously commented on this “puddle chemistry” experiment in his blog post:  

Making Science Personal

To encourage the persistence of underrepresented populations in STEM begins in gateway science courses like general chemistry, Stephanie N. Knezz shares her thoughts on .

To show the role of science in our daily lives, Manuel F. Molina and José G. Carriazo explore .

Shaking the Archives: The Blue Bottle Experiment

This issue includes a demonstration by Nicolas Dietrich, Kritchart Wongwailikhit, Mei Mei, Feishi Xu, Francisco Felis, Abderrahmane Kherbeche, Gilles Hébrard, and Karine Loubière that involves . It is a twist on the popular “blue bottle” experiment,  in which a solution containing glucose, NaOH, and methylene blue turns blue when shaken and becomes colorless while standing (a video of this can be seen as part of Michael Morgan’s ChemEd X post ). This demonstration was popularized by J. Arthur Campbell in 1963 as a way to introduce concepts of kinetics, mechanisms, catalysis, and steady-state conditions (). Over the years, discussions of and variations on this demonstration have appeared on the cover:
