If five extractions with 100 ml portions of ether extract 90% of a solute from an aqueous solution, what fraction of the solute will ten similar extractions remove? If you wish to extract aqueous acetic acid into hexane, is it more effective to adjust the aqueous phase to pH 3 or pH 8? Explain your answer. Three extractions with 50 ml portions of chloroform removed 97% of a solute from 200 ml of an aqueous solution. Calculate the partition coefficient of the solute: KD =Cchloro/Caq.
