Simple Distillation

• What physical separation technique is described in the video?

  Simple distillation
• What is the purpose of simple distillation?

  To separate a dissolved solid from a liquid
• What is an aqueous solution?

  A solution in water
• What happens to the water during crystallization?

  It evaporates, leaving solid crystals
• What is the first step in simple distillation?

  Evaporate the liquid by heating
• What is the second step in simple distillation?

  Condense the vapor back to liquid
• What apparatus is used to carry out simple distillation?

  A flask, glass tube, and condenser
• What role does the condenser play in simple distillation?

  It cools the vapor to turn it back to liquid
• How does the thermometer function during simple distillation?

  It measures the temperature of the vapor
• What happens to the vapor as it passes through the condenser?

  It condenses back into a liquid
• What is produced at the end of simple distillation?

  Crystals of solid and liquid in a beaker
• Why is simple distillation not commonly used to produce drinking water from seawater?

  It requires a great deal of energy
• What are the two stages of simple distillation?

  1. Evaporate the liquid by heating
  2. Condense the vapor back to liquid
• What are the components of the apparatus used in simple distillation?

  • Flask for the solution
  • Continuous glass tube
  • Condenser with cold water
  • Thermometer to measure vapor temperature
• What is the difference between simple distillation and fractional distillation?

  • Simple distillation: separates liquids with different boiling points
  • Fractional distillation: separates mixtures with closer boiling points
