Question

why is the extraction method used in organic chemistry lab?

Answer 1

when you have a mixture of compounds like a Acid nuetral or base nuetral or acid base

these compounds you can separate easily using the extraction method

suppose you have a mixture of compounds in organic layer ther acidic and nuetral in nature

now add 5% NaHCo3 solution to your organic layer shake amd separate both the layers using separating funnel

now acidic compound foms the corresponding sodium salt and come in to the water layer to this layer add the 5% HCl you can regenerate your acidic compound

and nuetral compound only there in the organic layer

in this way it is very useful
