Simple Distillation

• What is the purpose of simple distillation?

  To separate a dissolved solid from a liquid while keeping the liquid.
• What are the two stages of simple distillation?

  • Evaporation of the liquid by heating
  • Condensation of the vapor back to a liquid by cooling
• What is an aqueous solution?

  A solution in water.
• Why is crystallization used to separate a dissolved solid from a liquid?

  It separates the dissolved solid from the liquid by forming crystals.
• What is the main limitation of using simple distillation for producing drinking water from seawater?

  It requires a great deal of energy.
• What apparatus is used in simple distillation?

  • Flask for the solution
  • Continuous glass tube
  • Condenser with cold water running through it
  • Thermometer
• How does the temperature reading on the thermometer change during simple distillation?

  It increases as the liquid evaporates.
• What happens to the vapor in the condenser during simple distillation?

  • The vapor cools down
  • It condenses back into a liquid
  • The liquid is collected in a beaker
• What is the role of the cold water in the condenser during simple distillation?

  The cold water keeps the internal glass tube cold, facilitating the condensation of vapor.
• What is the difference between simple distillation and fractional distillation?

  • Simple distillation separates a single liquid from a solution
  • Fractional distillation separates multiple liquids based on different boiling points
