Discussion Forum : Mass Transfer - Section 6 (Q.No. 39)
39.
In a liquid-liquid extraction, 10 kg of a solution containing 2 kg of solute C and 8 kg of solvent A is brought into contact with 10 kg of solvent B. Solvent A and B are completely immiscible in each other whereas solute C is soluble in both the solvents. The extraction process attains equilibrium. The equilibrium relationship between the two phases is Y* = 0.9X, where Y* is the kg of C/kg of B and X is kg of C/kg of A. Choose the correct answer.

Material Balance :
2=10y*+8x
Y*=0.9x
Solving that ..y*=0.10588.
So the transfer of C=(y*)*B.
=0.10588*10,
=1.0588.
So correct answer is (B).
2=10y*+8x
Y*=0.9x
Solving that ..y*=0.10588.
So the transfer of C=(y*)*B.
=0.10588*10,
=1.0588.
So correct answer is (B).

I think the answer is B because Y* = 18/17.
