Organic Chemistry Lab: Base Extraction 1. If you had a mixture that contained benzoic acid, 2-naphthol and napthalene how would the process of separating these three compounds differ from separating benzoic acid and naphthalene? 2. Compare the solvents used for extraction to a mixed solvent for recrystallization. a. Why would extraction not work if two miscible solvents were used? b. Why would crystallization not work if two immiscible solvents were used? 3. Compare and contrast the separation and purification of benzoic acid from: a. Malonic acid b. 1,4-dichlorobenzene. 4. What would happen if 0.5 M HCl was used to neutralize a NaOH solution containing benzoate ions? Consider the following when answering: a. Total Volume b. pH c. solubility of benzoate; solubility of benzoic acid 5. What would happen if the pH of an aqueous solution contaning benzoic acid was at 4.0 and not at 2.0?
