Complete the extraction scheme for the separation of 1,2-dichlorobenzene, phenol (pKa = 10), and pyridine. 2. Sodium bicarbonate (NaHCO3) can be used as a base to extract carboxylic acids into the aqueous layer, but it cannot be used to extract most alcohols. Explain. 3. Explain the difference between extraction and washing. 4. Look up the densities and miscibility of hexane and water. See the miscibility chart from experiment 2. Would these two solvents work well together in an extraction procedure? Explain. Cl Cl OH N in ether add NaOH(aq) aqueous soln: ether soln: acidify with HCl add HCl(aq) aqueous soln: ether soln: basify with NaOH Component C extract into ether Component A Component B
