a. One can use pH differences to separate basic substances from non-basic ones. Which of the following would be suitable for use in the aqueous phase to achieve the separation of phenol from naphthalene: K2HPO4, K3PO4, (CH3)3NHCl, (CH3)3N, NaHCO3, Na2CO3? Explain your answer.
b.Which of these same materials (K2HPO4, K3PO4, (CH3)3NHCl, (CH3)3N, NaHCO3, Na2CO3) could be used in the aqueous phase to separate phenol from benzoic acid?
