Solvent extraction is being used by a student to separate a
naturally occurring triprotic acid, H3A (25g/L) from an organic
solution. The procedure involved shaking 75 mL of the solution with
100 mL of water and allowing the mixture to equilibrate in a
separatory funnel. The aqueous phase was then titrated in
triplicate with 1 M NaOH for which the following titre values were
obtained: 14.40 mL, 12.00 mL, 12.10 mL. Calculate the partition
coefficient of H3A between the organic solvent and water. Molar
mass of the triprotic acid = 321.7 g/mol
