Question

2. If you had an unknown organic solvent that was immiscible with water how could you tell which layer in the separatory funnel was the aqueous layer? (1) 3. Why are multiple extractions usually performed? (1) 4. In the separation of a mixture of benzoic acid and anisole both are dissolved in ether and added to a separatory funnel. Next, 5 mL of 3M NaOH is added. Draw the reaction equation for the reaction that takes place. In what layer do you find each compound? (2) 5. In the above extraction, the product found in the aqueous layer must be neutralized to recover the compound. If the only acid available is 1.5M HCl, approximately how much acid will be necessary to neutralize the solution? (1) 6. What is the boiling point of diethyl ether? What hazards are associated with it? (2)
