Assume that the distribution coefficient for compound X between chloroform and water is 2.8. If 50 mL of water that is initially 0.1 M in X is extracted with three 25-mL portions of chloroform:
a) What if the final concentration of X remaining in the aqueous phase?
b) How many millimoles of X remain in the aqueous phase?
c) If X has a MW of 156, how many grams remain in the aqueous phase?
d) If instead of using 25-mL portions of chloroform, one 75-mL portion has been used, how much of the solute would remain in the aqueous phase?
e) What can you conclude about the desirability of using one large portion or several small portions of solvent for extractions?
