Q1. Study the phenol/water phase diagram below and answer the following questions regarding systems occurring at 30 °C in equilibrium 66.8° Temperature (°C) 30 VIII 0 One liquid phase h AWW Water (A) Phenol (B) d W Two liquid phases 11% Phenol 63% Phenol C | | 0 g 1 20 40 60 i Phenol in water (% by weight) 80 100 A. Calculate the amount of phenol (g) in the water-rich phase and the phenol- rich phase at point (d) 24%w/w phenol in water, where the two liquid phases separate at 7% and 70% of phenol respectively, assuming total weight of system is 135g. B. What is the total amount of water (g) in the water-rich phase and the phenol- rich phase at 60%w/w phenol assuming total weight of system is 50g. C. Determine the concentration (i.e. %w/w phenol in water) at which the system separates into equal weights of water-rich and phenol-rich phases, and calculate the weight of phenol and water in these conjugate phases assuming total weight of system is 45g.

Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. species ОН HIO H₂O CH₂CICOO CH₂CICOOH CH₂O ΙΟ CH₂OH relative pH of 0.1 M aqueous solution 8 (highest) (Choose one) (Choose one) (Choose one) 1 (lowest) (Choose one) 7 2 X Ś
