SEPERATING SOLUTE AND SOLVENT

SEPERATING SOLUTE AND SOLVENT
2
Solute and solvent maintain their properties and
can be separated from the solution

• Simple methods
• Evaporation process where liquid changes into
  gas.
• If the solution is a liquid solid solution then
  the liquid turns to gas and leaves the solid
  behind.
• Example hard water drying and leaving the
  minerals (solutes) behind as white spots.
• Boiling process where liquid changes rapidly
  into gas.
• Each liquid has its own boiling point
• If the solution is liquid-solid the solid is
  left behind
• If the solution is liquid liquid they can be
  separated by boiling points.

Distillation

• Combines boiling with condensation to separate
  solute and solvent.
• Allows to collect both substances
• Works for liquid-solid solutions
• Works for liquid liquid solutions using different
  boiling points.

4
Distillation Process

• Solution is placed in a closed flask with a tube
  connected to the cork. (this way the vapor can
  only go out through the tube.
• Solution is heated.
• Liquid turns to gas and gas out into the tube.
• Gas cools and condenses turning into liquid
  again in the tube.
• Liquid falls into a second flask.
• One part of the solution was left behind in the
  first flask and the other is collected in the
  second.

In your binder

• Make and label a diagram to show the
  distillation process.
• Make a diagram showing the water cycle. Label it
  and explain why it is considered a distillery.
• Draw several ways of desalination (Separating
  salt from salt water or ocean)
• Homework Read pages 152- 160 and define bold
  words.
