Two weak acids, HA and HB, have K4 values of 1.0 E-6 and 3.0 E-4. Their partition coefficients between water and ether are 12.2 for HA and 8.3 for HB. How many extractions are required (using Vether/V water = 1) for the removal of HA (more than 99% from an aqueous solution, while retaining HB (≥ 99%) in the aqueous solution
