Question
Chapter 3.2, Problem 12E
Interpretation Introduction
Interpretation:Decolorization of colored solution should be explained.
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.
