Question
Chapter 3.2, Problem 32E
Interpretation Introduction
Interpretation:
The set of standard step by step instructions for recrystallization of the stilbene from ethanol needs to be done to obtain the maximum pure yield of the product.
Concept Introduction :
Recrystallization is defined as a technique which is used to purify the chemicals. This is done by dissolving the impurities and compounds both in a solvent, the compound needs to be recrystallized can be removed from the solution.

Contrast the physical appearance of the crude material before the recrystallization and that of the material isolated after recrystallization.
When isolating the solid after recrystallization using vacuum filtration what solvent should you use to aid in the rinse from the Erlenmeyer flask to the vacuum filter funnel? (Only pick one answer)
Group of answer choices:
Cold ethyl acetate
Cold ethanol
Hot ethyl acetate
Hot ethanol
Hot water
Cold water
None of the above, it should not be risned
what is the purpose of steam distillation? and what are the factors involved ?
