PROBLEM 3: Water and phenol are mixed and the phase diagram is shown below (FIG. 3). a. How many phases will exist in the mixture that results by mixing 50 g of phenol and 100 g of water at 55°C? b. What is the highest temperature in which phenol and water will form two-layered system? What is the critical concentration? c. Point A in the diagram corresponds to a two-layered mixture containing 40 g phenol and 100 g water a 42°C. What is the concentration (g phenol in 100 g water) of the phenol-rich layer?
