2. SEPARATION OF MIXTURES
Conditions and processes involved

3. SEPARATION OF MIXTURES
• SEPARATION OF MIXTURES
• There are five types of mixtures. They are:
1. Solid-Solid mixture
2. Liquid-Liquid mixture
3. Solid-Liquid mixture
4. Complex mixture
There are two nature of mixtures generally. They are:
1.Homogenous Mixture
2.Heterogenous Mixture

4. SEPARATION OF MIXTURES
Processes of Separation of two Solid-Solid mixtures:
1.By Magnetic Separation-This is only possible when
one of the component is magnetic. A magnet is
placed near the mixture and the magnetic
component is separated as separated as shown
below:

5. SEPARATION OF MIXTURES
2.By Sublimation- In this process, the solid state of
matter directly changes into gaseous state of matter.
For this method one component should be sublime
and on heating the mixture is separated. The
picture below shows the above process:

6. SEPARATION OF MIXTURE
Processes of separation of two Liquid-Liquid mixtures:
1.By Distillation- If the liquid in the mixture are miscible
and have different boiling points then they can be
separated by distillation. Complete separation is
possible if the b.p of the liquid differ by 30 degree C
or more.

7. SEPARATION OF MIXTURES
2. By Separating Funnel- If the liquids are miscible then
they are put in a separating funnel then it will
separate the mixture of two liquids into two distinct
layers.

8. SEPARATION OF MIXTURES
Processes of separation of Solid-Liquid mixture:
1.By Filtration- This process is only applicable when
solid is insoluble in the liquid and thus forms a
heterogeneous mixture. Filter paper is used in this
process.

9. SEPARATION OF MIXTURES
2. By Evaporation-This method is suitable when one of
the component is a soluble solid and the other a
liquid that forms a homogenous solution with that
solid component. The liquid can be easily evaporated
and its loss can be ignored.

10. SEPARATION OF THE MIXTURES
Process of separation of Complex mixtures:
1.Chromatography-Used mainly to separate color by
adsorption and partition.
