Corny sound effects, but very helpful video! The dipping trick isn't written in my lab text, so thanks for adding that to my "toolbox."

basically no. while your seed crystal might be slightly impure - the bulk of the material wont contain the impurity. When compounds crystallize it is a sign of high purity

Anyone else watching for CHEM53 at Tufts?

Somewhat true, but inaccurate, if the process is performed incorrectly, or the original crystals formed in less than ideal conditiona, a number of things can occur, for instance impurities can become encapsulated within the crystals. The technique demonstrated in the video is REcrystallization, obviously had the original crystals been "high purity" purification through recrystallization would serve no purpose. Perhaps crystallization is a sign of at least relatively fair purity.

Thank you for a most helpful video.

Are you kidding me? Even one who hasn't far decided has decided as far looked think like it. Looking more even a little decided far is a beautiful sight.
