Consider the equilibration of a weak base B (Kb = 7.63 x 10-2) between water (phase 1) and benzene (phase 2). Which expression represents D, the distribution ratio? B represents the unprotonated form of the base and BH+ represents the protonated form of the base. [B]2 [B]₁ O [BH+]2 [BH+]₁ [B]2 [B]₁ + [BH*]₁ D= [BH]2 [B]₁ + [BH+]₁ Calculate D at pH 8.41 if KD = 49.0. Which expression represents KD, the distribution constant? B represents the unprotonated form of the base and BH represents the protonated form of the base. [B]2 [B]₁ + [BH+]₁ [BH]2 [B]₁ + [BH]1 [BH+]2 [BH*]1 [B]2 [B]₁ Will D be larger or smaller at pH 6.00 than at pH 8.41? smaller
