Homework Answers
Percent of recovery in the recrystallization process depends on the nature of the solvent that you choose. That is, a solvent should be chosen in such a way that your compound should be insoluble or sparingly soluble in the solvent at room temperature and completely dissolve in the higher temperature. The impurities should be completely soluble in the solvent at both room temperature and at higher temperature.
Seeing the percentage of recover, I feel that you should change the solvent and try to recrystallize it. It has nothing to do with the impurity contents.

assuming there were no significant experimental errors, do you think the percent recovery of a recrystallization is the same as the percent of the impure sample that is the desired compound? for example, if you recovered 90% of the sample, does that mean 10% of the sample was the impurity? why or why not?

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 does the intercept (3.3735438) tell us? Is it meaningful Select one: O a. It is greater than zero, so there is a positive relationship between beds and risk. This is meaningful in this context. O b. It tells us that the lowest possible risk is 3.3735438. That is meaningful in this context c. It tells us that a hospital with 0 beds is expected to have a risk of 3.3735438. That is not meaningful in this context. O d....

Tell us of a problem with a product which bothers you. How would you use technology to solve the problem? - Propose more than one potential solution (max 3) Compare and choose the best solution for the problem How would you measure whether the chosen solution is working? What might be the reason for this chosen solution to fail ?
