Answer to Question #90151 in General Chemistry for Ida

Question

What is the name of the technqiue that is used to cause a substance dissolved in one liquid to leave that liquid and enter another?

Answer 1

Liquid–liquid extraction (LLE), also known as solvent extraction is a method to separate compounds or metal complexes, based on their relative solubilitiesin two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic. The transfer is driven by chemical potential.
