Lesson 3 Flashcards
In preparing coffee using the Barako coffee
beans, you may pour the boiled coffee mixture
into a piece of cloth. Which method is being
illustrated?
Filtration
In a laboratory setting, you have a mixture of
different colored pigments. Which technique
would you likely use to separate these pigments
for analysis?
Chromatography
When separating a mixture of sand, salt, and
water, what sequence of techniques could be
applied to obtain the pure salt?
Filtration, Evaporation, Decantation
When considering the separation of a mixture
through distillation, what property of the
components is essential for the process to be
effective?
Boiling point
Suggest a separation method to be done on the
following mixture to separate its components.
Perfume
Cartridge ink
Crude oil
Rock salt and cornstarch
Saltwater and sand
Perfume – Use distillation
Cartridge ink – Use chromatography.
Crude oil – Use fractional distillation
Rock salt and cornstarch – Use dissolution and filtration
Saltwater and sand – Use filtration and evaporation.
o In this process, a solution is heated until it boils.
o Once it boils, the liquid solvent starts to
evaporate and leave behind the solid solutes.
Evaporation
can be used to separate
solutions.
Recrystallization
refers to the amount of substance
that can be dissolved in a given solvent at a
certain temperature.
Solubility
used to separate
components of liquid
solutions
distillation
setup
separates
components of a solution based
on differences in boiling points
between the two liquid
components.
Distillation
Types of Distillation
Simple distillation
Fractional distillation
Vacuum distillation
Steam distillation
is used when there is a large difference in the
boiling points of the components of the solution
Simple distillation
is used when there is a relatively small
difference in the boiling points of the components of the solution.
Fractional distillation
is used for compounds with very high boiling
points.
Vacuum distillation
is used for compounds that are heat-sensitive.
Steam distillation
is the
laboratory glassware that
is used to contain the
mixture that will be
distilled.
Distilling flask
Aids in the
condensation of the
vapors or the change of
vapors to liquids
Condenser
The pure substance with the lower boiling point is called the
distillate or the product of distillation.
The substance that remains in the distilling flask after
distillation is called the .
residue
There must be a large difference in
the boiling points of the liquid
components in order to perform
distillation as a separation technique
for liquid mixtures.
TRUE
is a separation
technique that relies on the
differential partition of the
components between the two
important phases in
Chromatography
The result of a chromatography experiment is called a
chromatogram
Separation of Homogeneous Mixtures
Evaporation
Recrystallization
Distillation
Chromatography
Separation of Heterogeneous Mixtures
Manual picking
Sieving
Magnets
Filtration
Sedimentation
Centrifugation
using your
hands or tongs can be done in
separating the components of
these kinds of mixtures.
Manual picking
exploits the
difference in particle size of
solids.
Sieving
can be used to
attract magnetic materials.
Magnets
is a process of
separating solids from liquids
by allowing the mixture to
pass through a filtering
materia
Filtration
The coffee grounds collected on the filter paper are
known as the _______ while the brewed coffee is known
as the ________.
residue
filtrate
is the process
in which suspended solids will
eventually separate from
liquids by gravity.
Sedimentation
Once the solid particles settle
at the bottom, the liquid may
be separated through
decantation.
An easier way to separate
immiscible liquids is by using
a
separatory funnel.
is a
process in which the
suspension or colloid is
rotated at very high
speeds.
Centrifugation
In the chemical and
pharmaceutical
industry, _______are used to
purify chemicals to
acceptable standards.
separation
techniques
In the petroleum
industry, _______ is
often used as a method
to purify products.
o A refinery is an
industrial site that is
used to refine
substances like oil,
alcohol, and other
substances. c
distillation
In the wastewater industry, separation techniques
such as _________ are used to recover
water from used water.
sedimentation, centrifugation,
microfiltration, and distillation
In the field of health
and medicine,
________ is used
to separate the
components of blood or
urine for further
laboratory testing.
centrifugation
Identify the separation techniques
1. colored clothes from white clothes
2. chalk and water
3. boiled noodles in water
4. sand and gravel
5. Baby oil and water
manual picking
