Question
mass of unknown crude for acid and neutral is 0.03 grams mass of unknown recrystallized for acid and neutral is 0.03 grams. I need help in finding overall percent
Experiment 3
Using acid-base extraction to separate a mixture
Assuming that your unknown mixture is composed of exactly 50% acid compound and
50% neutral compound, complete the table below. Show all calculations - you may
handwrite your calculations.
Note: "overall percent recovery" compares how much of each component you started with
in the mixture to the final mass obtained after recrystallization. In addition, 30 mg of crude
compound was reserved prior to recrystallization and should be accounted for in some way
when calculating the overall percent recovery of the compound from the mixture.

Based on your melting point ranges of your crude products as well as the appearance of the
TLC plates for your crude products, was recrystallization necessary to purify your acid
and/or neutral product? Why or why not? Explicitly include all relevant data for each
component of your answer.
Hint: the difference in the two temperatures of a melting point range tells you something
important about the purity of the compound.
