Question
Chapter 3.2, Problem 30E
Interpretation Introduction
Interpretation:Seldom use of high-boiling solvents as recrystallization solvents should be determined.
Concept introduction:Recrystallization is technique that is used for purification of organic compounds. This process includes dissolution of solid in specific solvent at high temperature and then crystals are made again by process of cooling. Temperature of crystals is decreased to allow impurities to remain in solution only.

More than one answer may be correct. Using ice to cool the sample will speed up the crystallization process so that large crystals will be formed. It is important that the sample is dissolved in just enough hot solvent. O Ideally the hot solvent used will keep the impurities dissolved OR not dissolve them at all. Enough cold solvent should be added to dissolve the sample BEFORE heating it past its boiling point.arrow_forward
