The critical concentration at the upper critical temperature

Reference no: EM13341479

Two liquids, A and B, show partial miscibility below 52.4 C. The critical concentration at the upper critical temperature is x=0.459, where x is the mole fraction of A. At 40.0 C the two solutions in the equilibrium have x=0.22 and x=0.60, respectively, and at 42.5 C the mole fractions are 0.24 and 0.48. Sketch the phase diagram. Describe the phase changes that occur when B is added to a fixed amount of A at (a) 48 C (b) 52.4 C
