Question
Chapter 3.3, Problem 6E
Interpretation Introduction
Interpretation:Difference between mixed melting point of compound A and compound B than that of pure A or pure B should be explained.
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. If two compounds have approximately same melting points, their melting points can be determined by mixed melting point.

What effect does the presence of impurity have on the melting point?
2) Explain why it is common practice to determine a melting point on an unknown compound rapidly first, and then to rerun the melting point slowly.
A student was trying to prepare acetaminophen in the laboratory. She found a melting point range of 169-173. The melting of acetaminophen is reported to be 168-172c. How could the student have verified that the produce is acetaminophen?
Retake the sample melting point with more material in the sample.
Ask the lab partner to measure the melting point of the sample.
