Experiment 2: Recrystallization Results and Discussion
This experiment uses recrystallization to purify an impure sample of an organic compound called acetanilide. Throughout the experiment, this data was obtained.
In order to obtain a mixture that could be efficiently filtered, 1.577 grams of acetanilide was measured out and dissolved in hot water.
A hot vacuum filtration was then run to remove most of the insoluble impurities found in acetanilide. At the end of the hot vacuum filtration, a portion of the insoluble impurities were filtered out onto the filter paper.

A hot vacuum filtration was then run to remove most of the insoluble impurities found in acetanilide. At the end of the hot vacuum filtration, a portion of the insoluble impurities were filtered out onto the filter paper.
These impurities looked somewhat like grains ofsand. Following the hot vacuum filtration, the filtrate remaining was boiled again to completely dissolve the acetanilide and then left to cool slowly.
Once the solution cooled to room temperature, the solution was placed in an ice-water bath to increase the recovery of acetanilide.
