Answer the following questions: a. Why should know the distribution coefficient in order to determine the minimum ratio of extraction solvent to feed solvent? b. Why is the selectivity of solvent >1? c. If selectivity is unity in liquid extraction, why would there be no separation that will occur? d. Why will the solvent dissolve very little of the solute if a large quantity of solvent is required to extract the solute?
