This document discusses different techniques for separating mixtures: magnetic attraction, filtration, evaporation, distillation, and paper chromatography. It explains that mixtures contain two or more substances and can be easily separated. The techniques are then defined: magnetic attraction separates mixtures containing magnetic materials; filtration separates insoluble solids from liquids; evaporation separates dissolved solids from liquids; distillation separates liquid mixtures with different boiling points; and paper chromatography separates components in essential oils. Examples of each technique are provided.

2. Separation of MixtureS
 Identify the different ways of separating
mixtures.
 Determine how the different ways are
used to separate mixtures.
 Identify the ways in which magnetic
attraction, filtration, evaporation,
distillation and paper chromatography
can be used in daily life.

3. Separation of MixtureS
 Mixtures are matter that are made up of
two or more compounds and/or elements.
 They can be easily separated.
 Suspensions and solutions are mixtures.

5. Separation of Mixtures
Magnetic Attraction
Separating mixtures containing magnetic
material like iron, cobalt and nickel.

6. Separation of MixtureS
Evaporation
Separating mixture of dissolved solids
from a liquid.
Heat is applied to quicken evaporation
but NOT to cause decomposition.

9. Separation of MixtureS
Filtration
Separating mixture of un-dissolved
solids from a liquid.

10. Some Filtration Systems

11. Separation of MixtureS
Distillation
Separating liquid-liquid mixtures of
different boiling points.
Temperature tells the type of vapor that
is entering the condenser.

12. Laboratory
DiStiLLation Setup
Stone chips
are added
into the liquid
to allow even
and uniform
boiling
Cold and hot water
enters from the
bottom and top of
the condenser
respectively. Water
will gain heat as
vapor condenses.
Warmer water is
less effective in
condensing vapor
Thermometer
at the
entrance of
the condenser
indicates the
boiling point
of the type of
vapor entering
it

17. Separation of Mixtures
Conclusion
 5 simple methods of separating mixtures.
 Different methods for components of
mixtures with different properties.
 Separating mixtures produces better
understanding of mixture.
 Man can produce useful
mixtures/components from raw
components/mixtures.
