Question
Chapter 3.3, Problem 8E
Interpretation Introduction
Interpretation:Modifications that can be made in capillary tube to obtain melting point of compound that sublimes before it melts 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.

Describe how fractional distillation can better purify a mixture of liquids by discussing a liquid vapor phase diagram. Draw a liquid vapor phase diagram and use this in your answer.
Due to the fact that the liquid you used was a volatile one, it will not completely recondense. Some of the liquid remains in the vapor phase, even at room temperature. If you were able to correct for this by making the vapors recondense completely, would your final molar mass value be greater than, less than or the same as the value you determined? Explain your reasoning.
Why would industry prefer to purify solids by sublimation or zone refining rather than recrystallization? (Hint: is there anything wasteful about recrystallization)
