Homework Answers
Above the binodal curve, a one phase solution exists and below it, a two phase solution.
Hence, at 0 0C two phase and at 15 0C one phase

b. You have prepared a solution of water-soluble polymer, and wish to isolate the polymer from the water by freeze drying it. This process involves two steps: i) The temperature of the solution is dropped at ambient pressure to a temperature below water's triple point. ii) The pressure of the frozen solution is reduced until water spontaneously leaves the system With this above in mind, sketch a phase diagram of water showing regions of stability in its solid, liquid, and...

Consider the phase diagram below for a mixture of chloroform and methanol, looking at how the boiling point changes with composition at constant pressure. If you started with a solution that was Xchloroform = 0.1 at a temperature of 333 K, is it possible to use fractional distillation to purify this solution to nearly 100% chloroform? Approximately what concentration (in mole fraction) would you expect you could achieve through fractional distillation? Curves calculated by mod. UNIFAC (Dortmund) Temperature Minimum Azeotrope...
