A mixture of chloroform (CHCl3) and acetic acid at 18oC and 1atm (101.3 kPa) is extracted with water to recover the acid. Fortyfive kg of 35 wt% CHCl3 and 65 wt% acid is treated with 22.75 kg of water at 18oC in a one-stage batch extraction. (a) What are the compositions and masses of the raffinate and extract layers? (b) If the raffinate layer from part (a) is extracted again with one-half its weight of water, what are the compositions and weights of the new layers? (c) If all the water is removed from the final raffinate layer of part (b), what will its composition be? Solve this exercise using the following equilibrium data to construct one or more of the types of diagrams .
