Question

If an organic substance is extracted from water, the effectiveness of the extraction is greatly impoved by saturating the water layer with sald before extracting. Why is this?

Answer 1

The transport will be proportional to the concentration. Higher concentration faster extraction.

Answer 2

Salt ions (Na+ and Cl-) make the water even less hospitable to organic compounds that may be slightly soluble in water. Thus, if one partitions the compound between a water layer and, say, an ether layer, the ionic environment drives the compound out of the water.
