Homework Help: Principle of operation

Posted by Sheryl on Saturday, October 7, 2006 at 8:51pm.

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?

Sheryl

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