Problem 1. Phenol and water are partially miscible liquids. A mixture consists of phenol and water has the temperature transition from one phase to two phases as follows: % phenol 10 20 30 35 40 45 50 55 60 70 t (°C) 42 52 60 67 66 65 63 60 50 28 a) If 10 g phenol and 20 g water are put into a closed tube and keep at 60°C. Determine the number of phases, composition of each phase and mass of each phase at equilibrium. (2 phases; 30% and 55%; 4 g water phase and 26 g phenol phase) b) If 20 g of water was added into the tube and keep at 60oC, what will happen? (two phases -> one phase)
