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.
Statement 1: Boiling point rise is due to the colligative properties due to the presence of solid particles in the solvent. Statement 2: Boiling point rise is due to the increase in pressure at the bottom of the solvent due to hydro-static head of the column.
