A monoprotic acid with a Ka= 6.46E-5 has a partition coefficient of 5.6 (favoring octanol) when distributed between water and octanol. Find the formal concentration of the acid in each phase when 100mL of 0.10M aqueous acid is extracted with 39mL of octanol at (a) pH 4.00 (b) pH 8.00. (a) pH= 4.00 what is the M concentration in water? What is the M concentration in octanol? (b) pH= 8.00 what is the M concentration in water? what is the M concentration in octanol?
