Chapter 3.2, Problem 15E
Interpretation Introduction
Interpretation:Five criteria that are used to select solvent for recrystallization 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.
