3. Introduction

4. Q1..So what did we learn about in the last
slide ?
• Ans1..
• We learned that components of a mixture can be separated into their natural form
or the form in which they were put in the mixture.
• These mixtures can be separated through many different separation techniques.
• The one in the video was distillation.

5. Q2..But then how can you separate them ?
Do you know how to do so ? explain.
• Ans2..
• We can separate the components through various separating solutions or
techniques.
• Lets take a example to answer the second part of the question. We have a mixture
of Acetone, Salt and Iodine.
• To bring them to their normal form we can here, use the technique of Distillation.
• We do this by taking a Biker with a Filter Funnel which has a Filter Paper in it
• After following these steps we put the solution in through the funnel. And by doing so
we see the acetone solution goes through the paper and the iodine and salt solution is
left behind in the Filter Paper

6. Q3..Can you give some Examples to
Separate the Components of a Mixture.
• Ans3..
• There are many examples to give to separate components from a mixture. Here
we go for them:-
• Crystallization
• Filtration
• Decantation
• Sublimation
• Simple distillation
• Fractional distillation
• Chromatography
• Centrifugation
• Magnetic separation
• Precipitation
Evaporation
Separating funnel

8. Some more Methods
 Adsorption, adhesion of atoms, ions or molecules of gas, liquid, or dissolved solids to a surface
 Centrifugation and cyclonic separation, separates based on density differences
 Chromatography separates dissolved substances by different interaction with (i.e., travel through) a material
 Demister (vapor), removes liquid droplets from gas streams
 Drying, removes liquid from a solid by vaporisation
 Electrophoresis, separates organic molecules based on their different interaction with a gel under an electric potential (i.e., different travel)
 Elutriation
 Extraction
 Leaching
 Liquid-liquid extraction
 Solid phase extraction
 Flotation
 Dissolved air flotation, removes suspended solids non-selectively from slurry by bubbles that are generated by air coming out of solution
 Froth flotation, recovers valuable, hydrophobic solids by attachment to air bubbles generated by mechanical agitation of an air-slurry mixture, which float, and are
recovered
 Deinking, separating hydrophobic ink particles from hydrophilic paper pulp in paper recycling

9.  Flocculation, separates a solid from a liquid in a colloid, by use of a flocculent, which promotes the solid clumping into flocs
 Filtration – Mesh, bag and paper filters are used to remove large particulates suspended in fluids (e.g., fly ash)
 Oil-water separation, gravimetrically separates suspended oil droplets from waste water in oil refineries, petrochemical and chemical plants, natural gas
processing plants and similar industries
 Magnetic separation
 Precipitation
 Sedimentation, separates using vocal density pressure differences
 Gravity separation
 Sieving
 Stripping
 Vapor-liquid separation, separates by gravity, based on the Souders-Brown equation
 Winnowing
 Zone refining
