An aqueous acetic acid solution containing 6.0mol/L6.0mol/L of acid is extracted with chloroform at 25C25C to recover the acid (B) from chloroforminsoluble impurities in the water. The water (A) and chloroform (C) are immiscible. If 10L10L of solution are to be extracted at 25C25C, calculate the percent extraction of acid obtained with 10L10L of chloroform under the following conditions: (a) the entire quantity of solvent in a single batch extraction; (b) three batch extractions with one-third of the solvent in each batch; (c) three batch extractions with 5L5L of solvent in the first, 3L3L in the second, and 2L 2L in the third batch. Assume the distribution coefficient for the acid =KDB=(cB)C/(cB)A=2.8 =KDB=(cB)C/(cB)A=2.8, where (cB)C=(cB)C= concentration of acid in chloroform and (cB)A=(cB)A= concentration of acid in water, both in mol/L
