Question: Based on chemical equilibrium, obtain a general expression for dependence of the distribution coefficient of a weak base bioproduct B (2) described by the equilibrium

Based on chemical equilibrium, obtain a general expression for dependence of the distribution coefficient of a weak base bioproduct B⁽²⁾described by the equilibrium expression in Exercise 8.43 that interacts with an organic solvent extractant X⁽¹⁾at the interface of an organic (1) Aqueous (2) System with valence z.

Data From Exercise 8.43

Derive general expressions for

(a) The partition coefficient, K^o_D, in an organic (1) aqueous–(2) LLE system for an un-ionized (neutral) form of a weak base given by
