Grading Key 1/2 point per item; 20 items; 10 points total 2. (2.5) Acetic acid (bp 118 o C) and toluene (bp(111 o C) form an azeotrope at a composition that is 28% n acetic acid. The boiling point of the azeotrope is 105 o C). Sketch the liquid vapor phase diagram of the system. Based on your diagram, what is the initial boiling point of a solution that is 75% acetic acid?
