An organic base (B) has a pKa of 6.950 and a distribution constant (KD), between water and ether, of 3.0. The organic base is extracted from 225 mL of a 0.175 M aqueous solution of B, that has been adjusted to a pH of 8.00, with 75.5 mL of ether. Only one extraction is performed. Calculate the concentration of the organic base (B) in the water phase after the extraction.
