Question

Consider the statement below about a student's crystallization procedure. "A student uses the correct amount of the appropriate recrystallization solvent and allows the solution to slowly cool to room temperature and then places it in an ice bath to complete crystallization. He then filters and collects the crystals. Some crystals stick to the sides of the flask so he washes the container with hot solvent." One step above caused a reduction in the yield. What part of the procedure described above should be corrected, and how?

Explanation / Answer

The answer correct is

The solvent used to wash was hot, use cold solvent to wash the crystals.
