Recrystallization involves dissolving the material to be purified (the solute) in an appropriate hot solvent. As the solvent cools, the solution becomes saturated with the solute and the solute crystallizes out (reforms a solid).
Web4 important concepts to consider in the process of recrystallization. solubility: dissolving purified solute in hot solvent to yield solution. saturation: as solvent cools, solution becomes saturated w/ respect to solute. exclusion: as crystal starts to form, impurities (insoluble) are excluded. nucleation: surface (seed crystal) where ...
Recrystallization is defined as the process in which grains of a crystal structure come in a new structure or new crystal shape. A precise definition of recrystallization is difficult to state as the process is strongly related to several other processes, most notably recovery and grain growth.
