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?
AThe entire amount of C is transferred to solvent B
BLess than 1 kg of C is transferred to B
CNo amount of C is transferred to B
DLess than 2 kg but more than 1 kg of C is transferred to solvent B
Correct answer
A. The entire amount of C is transferred to solvent B
Explanation
The correct answer is The entire amount of C is transferred to solvent B.
