Chapter 3.3, Problem 15E
Interpretation Introduction

Interpretation:Observation of original melting point as 150160 °C and melting point after recrystallization as 145145.5 °C should be determined.

Concept introduction:Melting point is temperature that involves conversion of substance from solid to liquid state. Both liquid and solid phases are present in equilibrium with each other at this temperature.

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.
