A 0.10 μM aqueous solution of a metal ion, M2+, is extracted into an organic solvent by 0.42 mM of the ligand L. Given that KL 1.3 x 104, KM = 8.0 x 104, Ka 2.0 x105, B 2.0 x 1022, and n = 2, calculate the distribution coefficient, D, for the extraction at pH 3.00 and pH 5.50. DPH-300 Number ☐ Number DPH-5.50 ☐ Calculate the fraction of M²* that remains in the aqueous phase, q, if 135 mL of 0.10 μM M2+ is extracted once with 5.0 mL of 0.42 mM L at pH 3.00. Number 4pH-3.00
