TOPIC: Methods of
Separating Mixtures
Essential Question:
What are the different
ways of separating
mixture?
Chemistry
What are the ways of
separating Mixture?
a.) Filtration
b.) Centrifuge
c.) Decanting
d.) Chromatography
e.) Distillation
f.) Density
Filtration can be
used to separate
an insoluble
substance from a
soluble substance
Ex. Coffee
grounds are
separated by
water through
filtration
Centrifuge
• A centrifuge is a
tool used to
separate matter
of different
densities.
• The centrifuge
spins rapidly.
• Ex. Separation
of solid matter
in blood from
the liquid
portion.
Decant
• To decant – pour
the liquids off
and leave the
solids behind
Chromatography
• Used to separate
components of a
solution
• Ex. Paper
chromatography
separate black
ink into the
colored dyes it
contains
Distillation
• A method of separating
substances that have
different boiling points
• Ex. Separating alcohol
from water
• Boiling pt of alcohol is
70 Celcius
• Boiling pt of water is
100 Celcius
Density
• Ratio of
mass and
volume
Update Notebook
• Paste or tape
that notes on
page 35
• On page 34
You are going to
draw all of those
techniques in
separating the
mixtures
Evaporation
can be used to
separate a
solute from
the solvent in
a solution
A magnet
• Can be used to separate a magnetic
substance from a non-magnetic
substance
