Introduction

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.

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 PaperTADA

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:-CrystallizationFiltrationDecantationSublimationSimple distillationFractional distillationChromatographyCentrifugation

Magnetic separationPrecipitationEvaporationSeparating funnel

Some more MethodsAdsorption, adhesion of atoms, ions or molecules of gas, liquid, or dissolved solids to a surfaceCentrifugationandcyclonic separation, separates based on density differencesChromatographyseparates dissolved substances by different interaction with (i.e., travel through) a materialDemister (vapor), removes liquid droplets from gas streamsDrying, removes liquid from a solid by vaporisationElectrophoresis, separates organic molecules based on their different interaction with agelunder an electric potential (i.e., different travel)ElutriationExtractionLeachingLiquid-liquid extractionSolid phase extractionFlotationDissolved air flotation, removes suspended solids non-selectively from slurry by bubbles that are generated by air coming out of solutionFroth flotation, recovers valuable, hydrophobic solids by attachment to air bubbles generated by mechanical agitation of an air-slurry mixture, which float, and are recoveredDeinking, separating hydrophobic ink particles from hydrophilic paper pulp inpaper recycling

Flocculation, separates a solid from a liquid in a colloid, by use of a flocculent, which promotes the solid clumping into flocsFiltrationMesh, 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 inoil refineries,petrochemicalandchemical plants,natural gas processingplants and similar industriesMagnetic separationPrecipitationSedimentation, separates using vocal density pressure differencesGravity separationSievingStrippingVapor-liquid separation, separates by gravity, based on the Souders-Brown equationWinnowingZone refining
