Miscibility
The miscibility usually indicates the capacity of various Liquide S to be mixed. The mixture obtained is homogeneous and the liquids are qualified the “miscible ones. ” Conversely, the substances are known as “not-miscible” if it cannot mix and form a heterogeneous solution. It is the case of the Huile and the Eau which form a emulsion. Solid phases can also form a “solid Solution” and present a character of total miscibility, partial or of immiscibility, studied through diagrams of phase. there is no rule checking miscibility between two liquids. if there is not-miscibility, the liquid with the least large density will float with the top of the other, one will observe two phases then.
Composed organic
In the made up organics, the length of the carbonaceous chain often determines relative miscibility with respect to the homologous members of Séries. For example, in the alcohols, the ethanol has two carbon atoms and is miscible with water and, the Octanol has eight carbon atoms and is not miscible with water. Nonthe misciblity of the octanol and water is used like normalizes for the balance of partition.
Miscibility can occur for a number of reasons. In alcohol, the Groupement hydroxyl can form hydrogen bonds with the Molécule S of water. In the Aldehyde S and Cétone S the hydrogen bond can form with only one pair of electrons on the atom of Oxygène carbonyl.
