METHODS OF SEPARATING MIXTURES Flashcards
(often by hand) takes advantage of
physical properties such as color and shape.
Mechanical Separation
takes advantage of the physical
property of magnetism.
Magnetic Separation
used to separate
solid particles of
different sizes.
Filtration
To pour off a liquid,
leaving another liquid
or solid behind. Takes
advantage of
differences in
density.
Decanting
The
separation of a
mixture of liquids
based on the physical
property of boiling
point.
Distillation
Vaporizing a liquid
and leaving the
dissolved solid(s)
behind. Used to
separate salt
solutions.
Evaporation
More dense components
sink to the bottom and
less dense components
float. The components
cannot be soluble within
each other.
Density Separation
Circular motion
helps denser
components sink
to the bottom
faster.
Centrifuge
Uses the property of
molecular attraction
(molecular polarity) to
separate a mixture.
Paper chromatography
Dissolved
substances
crystallize out of a
solution once their
solubility limit is
reached as
the solution cools.
Fractional
Crystallization
