WebbTranscribed image text: Recrystallization is particularly effective for separating organic compounds that have Osimilar molecular weights ionizable functional groups different … In chemistry, recrystallization is a technique used to purify chemicals. By dissolving a mixture of a compound and impurities in an appropriate solvent, either the desired compound or impurities can be removed from the solution, leaving the other behind. It is named for the crystals often formed when the compound precipitates out. Alternatively, recrystallization can refer to the natu…
