WebWhat is extraction. The process of transferring a solute from one solvent into another solvent. A separatory funnel contains the two immiscible liquids water and tetrahydrofuran. Use the given densities to determine which layer is on top and which is on the bottom in the binary mixture. tetrahydrofuran density: 0.89. Websolution, because the organic solvent (tert-butyl methyl ether) is not miscible in the basic aqueous layer. In step 3, the different layers are separated from one another. Since tert-butyl methyl ether is less dense than the aqueous layer, this layer is removed and treated further in steps 5 and 6.
