In the extraction of salicylic acid from water using dichloroethane, a student begins with 2.4 grams of the salicylic acid dissolved in 100 ml of water. after extraction with 20 ml of dichloroethane, drying and evaporation of the organic layer yielded 1.344 grams of salicylic acid. assuming the student was efficient and did not lose any material, what is the distribution coefficient (kd) for the system ? let kd = (concentration in organic solvent) / (concentration in aqueous solvent)
