WAY OF SEPARATION OF MIXTURES.
Mixtures are constituted by more than one kind of pure
form of matter, known as a substance .We can also say
that a mixture contains more than one substance.
Mixture Of Dry
Fruits Soil
Air is mixture of various
gases.
There are two types of mixtures
HOMOGENEOUS HETEROGENEOUS
In which constituents
present are uniformly
mixed and have no arise of
separation.
In which constituents
present may not uniformly
mix and have clear bound
arise of separation.
We have learnt that most of the natural substances
are not chemically pure.
Different methods of separation are used to get
individual components from a mixture. Separation
makes it possible to study and use the individual
components of a mixture.
• EVAPORATION
• CENTRIFUCATION
• DISTILLATION
• SEPERATING FUNNEL
• SUBLIMATION
• CHROMATOGRAPHY
• FRACTIONAL DISTILLATION
• COMPONENTS OF AIR
EVAPORATION
It can be used to separate solute from solvent.
We find that ink is a mixture of a dye in water .
Thus, we can separate the volatile component
(solvent) from its non-volatile solute by the
method of evaporation.
It can be used to separate :
• CREAM FROM MILK
• SQUEZZE OUT WATER FROM WET
CLOTHES
• BLOOD AND URINE TESTS
The centrifuge works on the principle of increasing
effective gravity (g's) to enhance the rate of settling
of suspended particles more dense than the buffer.
Effective gravity increases as you increase the
radius of your centrifuge arms, or with the square of
the rate of rotation.
SEPARATING FUNNEL
It is used to separate a mixture of two immiscible liquids.
It works on principle that immiscible liquids separate
out the layers depending on densities till denser liquid
will always form denser layer and lighter liquid will
form upper layers.
DISTILLATION
It is used to separate a mixture of two miscible liquids.
Distillation is a method of separating the constituents of mixture
(either a liquid or q gaseous one). It is a physical process and not a
chemical reaction using the different boiling temperatures of the
constituents to separate them from the others.
FRACTIONAL DISTILLATION
It's what produces gasoline for cars and spirits for cocktails.
It is based on the principle that every liquid has different
boiling point, none of the mixture of two or more miscible liquid
have same boiling point on the universe. So a mixture of two
miscible liquid will have different boiling point and on the basis
of this it is separated by the fractional distillation.
SUBLIMATION
It is used to separate mixture of salt and ammonium chloride.
It is technique which is used to separate those solids
from mixtures which directly pass to vapour state upon
heating and vapors on cooling give back solid again.
CHROMATOGRAPHY
It can be used to separate:
• Colours in a dye
• Pigments from natural colours
• Dugs from blood
It is the technique used for separation of those solutes
that dissolve in the same solvent.
SEPARATION OF INDIVIDUAL GASES FROM MIXTURE OF GASES
AIR
Compress and cool by increasing
pressure and decreasing temperature.
LIQUID AIR
Allow to warm up slowly in
fractional distillation column.
Gases get separated at different
heights.
OXYGEN ARGON NITROGEN
BOILING POINT(`C) -183 -186 -196
% AIR BY VOLUME 20.9 0.9 78.1
Flow diagram
shows the process
of obtaining
gases from air.

Separation of mixtures

  • 1. MADE BY : MOHIT GUPTA CLASS : IX G ROLL NO : 30 WAY OF SEPARATION OF MIXTURES.
  • 2. Mixtures are constituted by more than one kind of pure form of matter, known as a substance .We can also say that a mixture contains more than one substance. Mixture Of Dry Fruits Soil Air is mixture of various gases.
  • 3. There are two types of mixtures HOMOGENEOUS HETEROGENEOUS In which constituents present are uniformly mixed and have no arise of separation. In which constituents present may not uniformly mix and have clear bound arise of separation.
  • 4. We have learnt that most of the natural substances are not chemically pure. Different methods of separation are used to get individual components from a mixture. Separation makes it possible to study and use the individual components of a mixture.
  • 5. • EVAPORATION • CENTRIFUCATION • DISTILLATION • SEPERATING FUNNEL • SUBLIMATION • CHROMATOGRAPHY • FRACTIONAL DISTILLATION • COMPONENTS OF AIR
  • 6. EVAPORATION It can be used to separate solute from solvent. We find that ink is a mixture of a dye in water . Thus, we can separate the volatile component (solvent) from its non-volatile solute by the method of evaporation.
  • 7. It can be used to separate : • CREAM FROM MILK • SQUEZZE OUT WATER FROM WET CLOTHES • BLOOD AND URINE TESTS The centrifuge works on the principle of increasing effective gravity (g's) to enhance the rate of settling of suspended particles more dense than the buffer. Effective gravity increases as you increase the radius of your centrifuge arms, or with the square of the rate of rotation.
  • 8. SEPARATING FUNNEL It is used to separate a mixture of two immiscible liquids. It works on principle that immiscible liquids separate out the layers depending on densities till denser liquid will always form denser layer and lighter liquid will form upper layers.
  • 9. DISTILLATION It is used to separate a mixture of two miscible liquids. Distillation is a method of separating the constituents of mixture (either a liquid or q gaseous one). It is a physical process and not a chemical reaction using the different boiling temperatures of the constituents to separate them from the others.
  • 10. FRACTIONAL DISTILLATION It's what produces gasoline for cars and spirits for cocktails. It is based on the principle that every liquid has different boiling point, none of the mixture of two or more miscible liquid have same boiling point on the universe. So a mixture of two miscible liquid will have different boiling point and on the basis of this it is separated by the fractional distillation.
  • 11. SUBLIMATION It is used to separate mixture of salt and ammonium chloride. It is technique which is used to separate those solids from mixtures which directly pass to vapour state upon heating and vapors on cooling give back solid again.
  • 12. CHROMATOGRAPHY It can be used to separate: • Colours in a dye • Pigments from natural colours • Dugs from blood It is the technique used for separation of those solutes that dissolve in the same solvent.
  • 13. SEPARATION OF INDIVIDUAL GASES FROM MIXTURE OF GASES AIR Compress and cool by increasing pressure and decreasing temperature. LIQUID AIR Allow to warm up slowly in fractional distillation column. Gases get separated at different heights. OXYGEN ARGON NITROGEN BOILING POINT(`C) -183 -186 -196 % AIR BY VOLUME 20.9 0.9 78.1 Flow diagram shows the process of obtaining gases from air.
