Question

2. You have a solution of a phenol and a carboxylic acid dissolved in dicholormethane (density: 1.325 g/mL) What aqueous solution could you use to extract just the carboxylic acid? Explain. (4 points) a. b. During the extraction described above, which layer would be the top/bottom? Why? (3 points) 3. Why is it important to add a drying agent like anhydrous sodium sulfate to an organic layer (solution) that was just separated from an aqueous layer? (3 points) 4. Give two reasons why it is important to carry out the extraction procedures (or really any lab procedures) in the hood. (4 points)

can you answer #s 2, 3, and 4 please
