Assume solvents A and B are virtually insoluble in each other. Component C is soluble in both.

(a) Use the Scatchard-Hildebrand theory to estimate the distribution coefficient at low concentrations of C given as (mole fraction C in A)/(mole fraction C in B).

(b) If the phase containing A is 0.1 mol% C, estimate the composition of the phase containing B.

(c) If an extractor was designed and constructed, is the distribution coefficient favorable for extraction from B into A? Data:
