a. Construct an approximate boiling-point-phase diagram (with % composition on the x-axis and temperature on the y-axis) for this system. Include the boiling points of pure methanol, pure carbon tetrachloride, and the boiling point of the azeotrope on your diagram. b. Describe the behavior on distillation of a mixture that is 90% methanol and 10% carbon tetrachloride. 4. After one component of the mixture has distilled off, the temperature is observed to temporarily drop before it increases to the boiling point of the second component. Explain this temperature drop. 5. Ethylene diamine (bp 116C ) and water form a maximum boiling azeotrope (bp 120C ); the azeotropic mixture is 80% in ethylene diamine. SKETCH a distillation curve (volume on the x-axis and temperature on the y-axis) to show what you would expect to see should one distill 35mL of a 50:50 mixture of these liquids. Be as quantitatively accurate as possible (using graph paper)
