2) Draw the isobaric phase diagram at 1 atm of the following two-component liquid system: water (Boiling point = 100°C) and nitric acid (Boiling point = 86°C), with the mass percentage of nitric acid on the x-axis. When the liquid mixture contains 68 % nitric acid, an azeotrope with a boiling point of 120.5°C, is formed. Use the sketch to describe under which conditions pure nitric acid can be obtained by means of isobaric distillation.
