7.6: Solvent Partitioning (Liquid-Liquid Extraction)

 · If the two solvents do not dissolve in each other, then when they are mixed together, they will form two different layers. That''s exactly what we want. If we have a mixture of polar and nonpolar compounds, and we mix them together with water and, say, diethyl ether, then the polar compounds should migrate to the water layer and the nonpolar compound should migrate to the ether layer.

The dissolution and leaching of minerals: Mechanisms, …

 · The mechanism by acid attack does not explain the kinetic parameters of these reactions, that is, that the dissolution of these minerals is one-half order in ferric ions. Many of the alternative theories proposed pay no attention to the orders of reaction; instead, a mechanism is proposed without any account of the primary kinetic information, the orders of reaction.
