1. Separating Mixtures:
Filtration: Uses a porous barrier to separate
a solid (undissolved) from a liquid.
Examples: Sunflower seeds and water.
Black pepper and water.
Solid wastes and water.

3. Separating Mixtures:
Decantation: To separate immiscible liquids
(different densities) or a solid
which is settled at the bottom
of a liquid.
Examples: Sand & water.
Small rocks & and water.
Oil and water.
Diesel & water.
Oil & vinegar.
Use a separatory funnel.

5. Separating Mixtures:
Vaporization: A solid dissolved in a liquid (we
want to collect the solid only).
Examples: Salt dissolved in water.

6. Separating Mixtures:
Distillation: Is based on differences in
the boiling points (two liquids
or liquid + solid dissolved) and
you want to recover both.
Examples: Salt dissolved in water.
Alcohol dissolved in water.

8. Separating Mixtures:
Chromatography: To separate the components
of the ink spread through
the paper at different
rates (chromatography
paper).
