Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...

Recrystallization of Acetanilide was conducted using water as our solvent. First we had to choose a solvent based (water was chosen as our solvent due to it not dissolving acetanilide at room temp but dissolved it when heated) Then we performed recrystallizaation, vacuum filtration and then melting point measurements. For the post lab discussion for recrystallization of acetanilide report we have to address several different arguments. The ones below I'm not sure what to focus on to completely defend what...

What is the literature (known) melting point for acetanilide? A student performed a recrystallization to purify a crude sample from a reaction. The amount of crude material collected from the reaction was 13.56 grams. After the purification, the student collected 8.97 grams of extremely pure material. a. What is the percent recovery of the desired material? b. Is it possible to determine how much of the desired material remained in solution after the filtration? The solubility of acetanilide in hot...

In chemistry we always say that “like dissolves in like”. A perfect example of this is ethanol in water versus oil in water. Ethanol and water have very similar intermolecular forces, therefore we could say that they are very similar and that ethanol will dissolve in water. Oil and water have very different intermolecular forces, therefore they are not the same and oil will not dissolve in water. Based on this notion, would you predict that the ink in a...
