Q
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?
AA. The entire amount of c is transferred to solvent b
BB. Less than 2 kg but more than 1 kg of c is transferred to solvent b
CC. Less than 1 kg of c is transferred to b
DD. No amount of c is transferred to b
Correct Answer:
A. A. The entire amount of c is transferred to solvent b
