Information AboutMiscible |
|
In Organic Compound s, the length of the Carbon chain often determines miscibility relative to members of the Homologous Series . For example, in the Alcohol s, Ethanol has two carbon Atom s and is miscible with water, whereas Octanol has eight carbon atoms and is not miscible with water. Octanol's '''immiscibility''' leads it to be used as a standard for Partition Equilibria . This is also the case with Lipids , the very long carbon chains of lipids cause them to almost always be immiscible with water. Miscibility can arise for a number of reasons. In the alcohol examples above, the group can form Hydrogen Bond s with water Molecule s. In Aldehyde s and Ketone s the hydrogen bond can form with a lone pair of electrons on the Carbonyl Oxygen atom. In metals, immiscible substances are unable to form alloys. Typically, a mixture will be possible in the molten state, but upon freezing the metals separate into separate phases. This property allows solid precipitates to be formed by rapid freezing of a molten mixture of immiscible metals. One example of immiscibility in metals is copper and cobalt, where rapid freezing to form solid precipitates has been used to create Granular GMR materials. SEE ALSO |
