The ratio of concentrations in each solvent is constant, known as the distribution coefficient. Extraction efficiency can be improved by using smaller volumes of solvent and multiple extractions. Liquid-liquid extraction is used to isolate organic acids, bases, and metal ions by forming neutral complexes that transfer to the organic phase. Read ...

The least reactive components can be replaced by the more reactive ones. Therefore, an element's reactivity accelerates the displacement reaction. Because of this, zinc can easily replace copper in a solution, but copper cannot. Because of this, when a zinc rod is submerged in the copper sulphate solution, its bluish tinge disappears.
