The mixture will be primarily an unknown organic acid contaminated with a significant amount of an organic neutral compound. Student is required to separate and purify the organic acid. The melting point will be taken, and the samples will be returned to the instructor in a labelled vial.
Students must have a complete procedure written out in their notebook when they show up for lab. The instructor will check notebooks as the students enter the lab. Anybody without a satisfactory procedure will not be permitted to enter the lab. For the purposes of planning the procedure, students may assume that there are 9 mmol of acid in their sample.
To limit waste, each student will be given 20 mL of dichloromethane to use during the lab.
