and Melting Points Organic Chemistry 2423 Lab Report: Recrystallization Abstract: The purpose of this lab was to purify an unknown compound by recrystallization. Taking an unknown compound and identifying it by purifying it from its impurities through the use of hot gravity filtration. Then to determine the unknown you were to take the melting point. An unknown compound was recrystallized from hot water to produce 0.99 grams (67% recovery). The pure unknown compound had a melting point of 127.0-128

Solubility‚ Crystallization and Melting Point Determination Post-Lab Discussion Guidelines: Part 2A and 2C: Draw tables (as in textbook) showing which combinations were soluble/miscible and which were insoluble/immiscible. Explain why this is so. Why are certain chemicals soluble/miscible when others are not? Part 3A: Calculate % recovery (this is not the same as % yield – see handout from the first day of lab if you’re confused)‚ and determine melting point of your product. Discuss % recovery

We are defined by “natural law” which is the concept of God working through our hearts and minds to help us choose the right
