A 0.150 M aqueous solution of the weak inorganic acid HA was prepared from the pure compound, and three 50.0 mL aliquots were transferred to 100.0 mL volumetric flasks. Solution 1 was diluted to 100.0 mL with 1.0 M HClO4; solution 2 with 1.0 M NaOH, solution 3 with water. A 25.0 mL aliquot of each was extracted with 25.0 mL of n-hexane. The extract from solution 2 contained no detectable trace of A-containing species, indicating that A^- is not soluble in the organic solvent. The extract from solution 1 contained no ClO4- or HClO4 but was found to be 0.0454 M in HA (by extraction with standard NaOH and back-titration with standard HCl). The extract from solution 3 was found to be 0.0225M in HA. Assume that HA does not associate or dissociate in the organic solvent, calculate a.) the distribution ratio for HA between the 2 solvents. b.) the concentration of the species HA and A^- in aqueous solution 3 after extraction c.) The dissociation constant of HA in water.
