WebWhat is Recrystallization. The definition of recrystallization is a technique for the purification of compounds in which a compound is dissolved in a solvent and slowly cooled to form crystals, which are a purer form of the compound. Scientists use recrystallization to purify solids, typically products, from different chemical reactions. WebJan 11, 2024 · Updated on January 11, 2024. Mother liquor is a deprecated term from older chemistry texts that refers to the solution that remains after crystallization occurs and the crystals are removed. Initially, crystallization occurs in a supersaturated solution that is usually prepared by heating a solution and continuing to add solute until no more ...
