Recrystalization is a method of purifying an organic product. By creating an oversaturated solution in a small amount of solvent, organized crystals can be grown and filtered out of the solution while impurities will remain resolved. A second crop of crystals can sometimes be grown from the remaining supernatant solution as not all of the target compound will recrystallize. This lecture contains advice for choosing a solvent, tips and warnings for this lab, and some suggestions for troubleshooting the experiment if the compound wont dissolve at all or if no crystals appear.
