Regarding extraction, the heading is: Descripton of method. Principle of operation.

My description is: Extraction is based on the principle that a certain solute will dissolve in two immiscible phases, one of which is usually liquid. For example, where one liquid is water and the other is organic, an organic solute will be found mostly in the organic layer while a salt will be found mostly in the water layer when equilibrium occurs.

Sound okay?

Sounds OK, however, the term salt could be better amplified. I think you mean hydrophilic compound.

Yes, you are correct. In the context of extraction, the term "salt" can be better specified as a hydrophilic compound. Hydrophilic compounds are those that have an affinity for water and are soluble in the aqueous phase. This means that in an extraction process where one liquid phase is water and the other is organic, hydrophilic compounds such as salts will predominantly dissolve in the water phase. Similarly, hydrophobic compounds, which have an affinity for the organic phase, will mainly dissolve in the organic phase during the extraction process. So, it would be more precise to refer to hydrophilic compounds instead of simply using the term "salt" in the description.
