2 Two liquids, \( A \) and \( B \), show partial miscibility below \( 52.4^{\circ} \mathrm{C} \). The critical concentration at the upper critical temperature is \( x=0.459 \), where \( x \) is the mole fraction of A. At \( 40.0^{\circ} \mathrm{C} \) the two solutions in equilibrium have \( x=0.22 \) and \( x= \) 0.60 , respectively, and at \( 42.5^{\circ} \mathrm{C} \) the mole fractions are 0.24 and 0.48 . Sketch the phase diagram. (5)

A phase diagram of a mixture of partially miscible liquids, A(l) and B(l) is shown on the right. The mixture is in a liquid state and fully miscible at P (310 K and xB = 0.90). (1) How many and what kinds of phases are present in ①, ②, ③, and ④? (4 points) (2) A sample of the mixture with xB = 0.90 is heated from the initial temperature of 310 K. When the mixture begins to boil at 367 K, small amount of the vapor was collected and cooled back to 310 K. Describe the physical states and chemical composition of the collected vapor at 367 K, 340 K, and 310 K. (6 points) Acetic acid dissociates partially into ions in water as shown below.

3) Liquid – Vapour phase diagrams of binary solutions are drawn to illustrate the composition in the liquid and vapour phases of the two volatile components. The diagrams below show this for the binary mixture of benzene and toluene, which form a nearly ideal binary solution: (A) as a function of Pressure, at 23°C and (B) as a function of temperature at P = 1 atm. The x-axis gives x(benzene). a) Identify the regions as vapour (V), liquid (L) or vapour+liquid (V+L), on graphs A & B. b) A solution is prepared by mixing 2.47 moles of benzene with 1.96 moles of toluene, at T = 23°C. The vapour pressure of pure benzene is 96.4 Torr and that of pure toluene is 28.9 Torr. i. What is the vapour pressure above this solution? ii. What are the mole fractions of each component in the vapour phase? iii. Illustrate these values in Graph A. iv. Use the result to explain how binary liquids can be separated in a distillation column.
