 5. Student W set up a distillation to separate the components

5. Student W set up a distillation to separate the components of 4.0mL of a cyclohexanetoluene mixture using the microscale apparatus described in the textbook. The student insulated the neck of the boiling flask and wrapped a damp piece of paper towel around the side-arm of the distillation head. The student then proceeded to heat the mixture rapidly on the sand-bath. The mixture was allowed to boil vigorously. When the first drop of distillate was collected, the thermometer reading was 65.5C. Within the next 5 minutes, a total of 23 drops of distillate had been collected into one vial and the thermometer reading had risen to 83.2C. At this point, the distillation was stopped because only approximately 0.5mL of liquid remained in the bottom of the boiling flask. Explain why this student should restart this distillation with a fresh sample. Discuss the mistakes that the student made, what effect those mistakes have on the separation, and what the student should do differently in their second attempt
