A monoprotic acid, HA, with a K, of 2.93 x 10-5 has a distribution constant (Kp) of 4.76 (favoring octanol) when distributed between water and octanol. Find the formal concentration of the acid in each phase when 100 mL of 0.100 M aqueous acid is extracted with 35 mL of octanol at pH 4.00 and pH 8.00.
