A monoprotic acid, HA , with a K a of 1.75 × 10 − 5 has a partition coefficient of 5.82 (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 43 mL of octanol at pH 4.00 and pH 9.00 .
