At the beginning of lab, we will have a discussion about liquid-liquid extractions, pka of weak acids and bases, and the conditions necessary to extract weak acids and bases into a non-polar solvent (or other non-polar material). You will then make predictions about the conditions (acidic/basic) necessary to extract the weak acid and base shown below into non-polar and polar solvents. Benzoic acid pk = 4.2 Under what pH conditions will Benzoic acid partition into a non-polar solvent? Ethyl 4-aminobenzoate (Benzocaine) minhas H2N H3N pk = 3.5 Under what pH conditions will Ethyl 4-aminobenzoate partition into a non-polar solvent
