Interpretation Introduction

Interpretation:Reason for undesirable use of filter paper in melting point determination should be determined. Also, difficulty in the same by presence of filter paper 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. If two compounds have approximately same melting points, their melting points can be determined by mixed melting point.

Briefly explain how slow cooling contributes to the formation of pure crystals during recrystallization.
a student obtained a solid product in a laboratory synthesis. to verify the identity of the solid, she measured its melting point and found that the material melted over a 12°C range. After it had cooled, she measured the melting point of the same sample again and found that this sharp melting point at the temperature that is characteristic of the desire product. why were the two melting point different? what was responsible for the change in the melting point?
