Simple Distillation

• What is distillation used for?


  To separate mixtures that contain liquids
• What are the two types of distillation mentioned?

  Simple and fractional distillation
• What is the process of simple distillation used for?


  • Separating a liquid from a solution
  • Involves heating the solution
  • Collecting the vapor after condensation
• What is the first step in the simple distillation process?


  Heat the solution to separate the liquid
• Where should the water enter and exit in the condenser during simple distillation?


  Water goes in at the bottom and out at the top
• What happens to the part of the solution with the lowest boiling point during simple distillation?


  It evaporates first
• What is distillation used for?


  To separate mixtures that contain liquids
• What are the two types of distillation mentioned?

  Simple and fractional distillation
• What is the process of simple distillation?


  1. Heat the solution.
  2. The liquid with the lowest boiling point evaporates first.
  3. The vapor is cooled and condenses back into a liquid.
  4. The liquid is collected, leaving the rest of the solution behind.
• What can simple distillation be used to obtain from seawater?


  Pure water
• What happens to the salt during the simple distillation of seawater?


  The salt is left behind in the flask
• What is a limitation of simple distillation?


  It can only separate liquids with very different boiling points
• What happens if the temperature exceeds the boiling point of the substance with the higher boiling point during simple distillation?


  They will mix again
• What method is needed to separate liquids with similar boiling points?

  Fractional distillation
• What is the setup for a simple distillation process?


  • Heat source
  • Flask containing the solution
  • Condenser with water in at the bottom and out at the top
  • Thermometer to monitor temperature
• Where should the water go in a condenser during distillation?


  In at the bottom and out at the top
• What is collected during the simple distillation process?


  The condensed vapor
• What is the purpose of the thermometer in the distillation setup?


  To monitor the temperature of the solution
• What is the final product of simple distillation from seawater?


  Pure distilled water
