A monoprotic acid, HA, with a K, of 1.76 x 10- has a distribution constant (Kp) of 3.99 (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 27 mL of octanol at pH 4.00 and pH 8.00. pH 4.00, in water: M pH 4.00, in octanol: M pH 8.00, in water: M pH in octanol: M
