Experiment: In the experiment: Mix together 74 g. (92 ml.) of n-butyl alcohol and 120 g. (120 ml.) of glacial acetic acid in a 500 ml. round-bottomed flask, and add cautiously 10 ml. of concentrated sulphuric acid (use a small measuring cylinder or a burette or a calibrated dropper pipette). Attach a reflux condenser and reflux the mixture on a wire gauze for 3-6 hours. Pour the mixture into about 500 ml of water in a separatory funnel, remove the...

Bromination of Acetanilide In a 25-mL Erlenmeyer flask, dissolve 0.68 g of acetanilide in approximately 4 mL glacial acetic acid. Record the exact amount of the limiting reactant that you used. Add a stir bar followed by 1.6 g pyridinium tribromide. Heat the mixture to ~60°C in a warm water bath for 10 minutes. After the 10 minutes, add 15 mL water and approximately 2 mL saturated sodium bisulfite solution to remove excess bromine, which shows by the disappearance of...

Suppose 1.00 g of NaOH is used to prepare 250 mL of an NaOH solution. Compare the expected molarity of this solution to the actual average molarity you measured in the standardization. What do you notice? Do you think the results would have been more accurate if a different type of acid or base were used in the standardization? Why, or why not? There are many different primary standards that could be used in a standardization titration. What are the...

and 4 mL EtOH in a 50 mL round bottom flask.
Dissolve 1.0 mL (8.6 mmol) of acetophenone into your
solution.
Add 1.0 mL (9.8 mmol) of benzaldehyde and a magnetic stir bar to
your flask. Clamp the flask
above a stir plate.
Monitor the reaction for 45 minutes by TLC. Acetophenone needs
to be diluted prior to TLC, and
cannot be spotted neat....

Questions and Exercises 1. In the course of reflux of the triglyceride in a sodium hydroxide solution you will notice a lot of foaming. Explain. What is left behind in the aqueous layer after filtration of the saponification product? The starting material and the product of the saponification reaction have similar melting points. How do you know you actually isolated a new product rather than just recovered the starting material? Give at least two different methods to...

Extraction of solids: Experiment outlined below
Draw a “roadmap” of the experiment, containing chemical
structures and “layers” (organic and aqueous). This should contain
the individual reactions occurring in each step, and show which
layer the various components are present. Make sure you think about
whether the acetaminophen, caffeine and aspirin are neutral,
protonated or deprotonated.
Preliminary separation obtain a sample (1.0g) of the mixture. weigh the sample and record it. this sample should consist of a 2:1:1 mixture (by mass)...
