Which of the following statements are false regarding simple distillation? When conducting a simple distillation, it is important to stir the distilling flask to prevent the solution from getting hot spots or bumping. The heat transfer between the hot plate and the distilling flask can be maximized by filling any gaps in the heating mantle with sand. The distilling flask cannot be distilled to dryness. When conducting a simple distillation of a known liquid mixture, the hot plate should be set to the average boiling point of the liquids.
