An aqueous acetic-acid solution containing 6.0 moles of acid per liter is to be extracted in the laboratory with chloroform at 25oC to recover the acid (B) from chloroform-insoluble impurities present in the water. The water (A) and chloroform (C) are essentially immiscible. If 10 liters of solution are to be extracted at 25oC, calculate the percent extraction of acid obtained with 10 liters of chloroform under the following conditions:(a) Using the entire quantity of solvent in a single batch extraction(b) Using three batch extractions with one-thud of the total solvent used in each batch(c) Using three batch extractions with 5 liters of solvent in the first, 3 liters in the second, and 2 liters in the third batch Assume that the volumetric amounts of the feed and solvent do not change during extraction. Also, assume the distribution coefficient for the acidwhere ( cB)C concentration of acid in chloroform and ( cB )A = concentration of acid in water, both in moles perliter.
