Distribution coefficient
What is the distribution constant for a Base (B) with a K = 3.0 and a pK a = 9. (phase 1 = aqueous, phase 2 =organic) For an amine with the previous characteristics, what is the formal concentration remaining in the aqueous phase if 50 mL of 0.01M aqueous amine is extracted with 100 mL solvent at pH 10? At pH 8?
What is the distribution constant for an Acid (HA) with a K = 3.0 and a pK a = 3. (phase 1 = aqueous, phase 2 =organic)
