3. The sequence for separating a solution of benzoic acid, naphthalene and 2-naphthol via extraction starts by washing the solution with aqueous sodium bicarbonate and follows with washing the resulting organic extract with aqueous sodium hydroxide. Why are the aqueous bases used in this order rather than the reverse order? Provide drawings and a brief explanation. The information below might be useful. OH Benzoic acid pka= 4.20 Base NaHCO3 NaOH 2-naphthol pka= 9.5 OH Conjugate Acid H₂CO3 H₂O naphthalene pka 6.4 16 |
