1.From the plots of the boiling point versus the volume of distillate in the simple distillation

experiments, what can you conclude about the purity of your product?
2. What is the effect on the boiling point of a solution (e.g., water) produced by a soluble nonvolatile substance (e.g., sodium chloride)? What is the effect of an insoluble substance such as sand or charcoal? What is the temperature of the vapor above these two boiling solutions?
3. In the distillation of a pure substance (e.g., water), why does all of the water not vaporize at once when the boiling point is reached?
4. Why is it extremely dangerous to attempt to carry out a distillation in a completely closed apparatus (one with no vent to the atmosphere)?
