Method of
Separating
Components of
Mixture

Method of separating components of mixtures
- is a procedure or process of segregating or
moving the constituent or part of a substance
which is made up of two or more pure
substances.

Methods of Mixture Separation
1) Mechanical Separation (often by hand) takes
advantage of physical properties such as color
and shape.
Example: Recycling Plastic, Paper, Metal

2) Filtration takes
advantage of
the physical
property of
the state of
matter. A
screen lets the
liquid particles
through, but
traps the solid
particles.
Example: Filtering Coffee, Spaghetti

 It is the process of separating the insoluble solid
from the liquid substance by allowing the
liquid to pass through a porous material called
filtering agent. The solid particles which are
retained in the filter paper is called residue, and
the clear liquid which passes through a
filtering agent such as filter paper is called the
filtrate

A filter can
also be used
to separate
solid
particles of
different
sizes.
(ex. a window
screen, an air
filter, a sand
sieve)

4) Decanting:
To pour off a
liquid, leaving
another liquid
or solid
behind. Takes
advantage of
differences in
density.
Example: To decant a liquid from a precipitate
or water from rice.

Decantation
This is a method used to separate the liquid
layer known as supernatant and a heavy
insoluble solid known as precipitate by
allowing the said solid to settle at the bottom
of the container then the liquid above the
solid is poured off carefully into another
container. In decantation process, the
mixture is being set aside and given enough
time the precipitate to settle at the bottom of
the container such as a beaker.

5 ) Distillation: The
separation of a
mixture of liquids
based on the
physical
property of
boiling point.
Example: the distillation of alcohol solution

 This is a process that involves the
evaporation and condensation of a liquid
solvent from a mixture or solution. This
method uses the difference in boiling points
of the components of a mixture.
The more volatile liquid in the mixture boils
first, evaporates, then condenses. The
distillate is the liquid formed from the
condensation of the vapor. Content of the
container should always be checked to
avoid drying up of the said container

6) Evaporation:
Vaporizing a liquid
and leaving the
dissolved solid(s)
behind. Used to
separate salt
solutions.
Example: Obtaining sea salt from sea water evaporation ponds

Separation
8) Centrifuge:
Circular motion
helps denser
components sink to
the bottom faster.
Examples: The separation of blood or DNA from blood

Separation
9) Paper
chromatography:
Uses the property of
molecular attraction
(molecular polarity) to
separate a mixture.
Different molecules
have varying
molecular attractions
for the paper (the
stationary phase) vs.
the solvent (the
mobile phase)
Example: the separation of
plant pigments and dyes

Chromatography
This process uses the difference in the degrees to which
substances are absorbed on the surface of an inert substance
such as a filter paper. A drop of ink or extract will be separated
into different components if it is placed at the end of a filter
paper and the tip of
the paper is allowed to barely touch the solvent. Separate
bands of colors, representing the different components will
appear on the paper. In doing this process, the filter paper
should ensure the touching of the solvent.
