Miscibility is a term in chemistry that refers to the property of liquids to mix in all proportions, forming a homogeneous solution. In principle, the term applies also to other phases (solids and gases), but the main focus on the solubility of one liquid in another. For example, water and ethanol are miscible in all proportions.

Impact from a water drop causes an upward rebound jet surrounded by circular capillary waves. ... “Grain alcohol” redirects here. ...

By contrast, substances are said to be immiscible if in any proportion, they do not form a homogeneous phase. For example, diethyl ether is fairly soluble in water, but these two solvents are not miscible since they are not soluble in all proportions. This article is about the chemical compound. ...

In organic compounds, the weight percent of hydrocarbon chain often determines the compounds miscibility with water. For example, among the alcohols, ethanol has two carbon atoms and is miscible with water, whereas octanol with a C₈H₁₇ substituent is not. 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. Analogous situations occur for other functional groups. Acetic acid is miscible with water, whereas valeric acid (C₄H₉CO₂H) is not. Simple aldehydes and ketones tend to be miscible with water, since a hydrogen bond can form between the hydrogen atom of a water molecule and the unbonded (lone) pair of electrons on the carbonyl oxygen atom. Benzene is the simplest of the arenes, a family of organic compounds An organic compound is any member of a large class of chemical compounds whose molecules contain carbon and hydrogen; therefore, carbides, carbonates, carbon oxides and elementary carbon are not organic (see below for more on the definition controversy...

Octanol is a straight chain fatty alcohol with eight carbon atoms and the molecular formula CH3(CH2)7OH. Although the term octanol usually refers exclusively to the primary alcohol 1-octanol, there are other less common isomers of octanol such as the secondary alcohols 2-octanol, 3-octanol and 4...

Carbonyl group In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom : C=O.

Immiscible metals are unable to form alloys. Typically, a mixture will be possible in the molten state, but upon freezing the metals separate into layers. This property allows solid precipitates to be formed by rapidly freezing 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. For other uses, see Copper (disambiguation). ... For other uses, see Cobalt (disambiguation). ... Founding results of Fert The Giant Magnetoresistance (GMR) is a quantum mechanical effect observed in thin film structures composed of alternating ferromagnetic and nonmagnetic metal layers. ...

Miscibility is partly a function of entropy, and so is seen more commonly in states of matter that are more entropic. Gases mix quite readily, but solids only rarely display miscibility. Two useful exceptions to this rule are solid solutions of copper with nickel (the cupronickel used in coins and specialty plumbing), and of silicon with germanium (used in electronics). Substances with extremely low configurational entropy, especially polymers, are unlikely to be miscible in one another even in the liquid state. Perdeuteropolyethylene is immiscible in polyethylene. For a less technical and generally accessible introduction to the topic, see Introduction to entropy. ... For other uses, see Nickel (disambiguation). ...
