The straight-chain carboxylic acids up to butanoic acid (with four carbon atoms) are miscible with water, pentanoic acid (with five carbons) is partly soluble, and hexanoic acid (with six) is practically insoluble, [5] as are longer fatty acids and other lipids; the very long carbon chains of lipids cause them almost always to be immiscible ...
The extent of solubility ranges widely, from infinitely soluble (without limit, i.e. miscible [2]) such as ethanol in water, to essentially insoluble, such as titanium dioxide in water. A number of other descriptive terms are also used to qualify the extent of solubility for a given application.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic.

The first is ITIES, "interfaces between two immiscible electrolyte solutions". [41] The second is droplet experiments. [ 42 ] Here a reaction at a triple interface between a conductive solid, droplets of a redox active liquid phase and an electrolyte solution have been used to determine the energy required to transfer a charged species across ...
“Soluble fiber helps improve our blood glucose (blood sugar) control and insoluble fiber helps regulate our bowel movements,” says Matthew Landry, P.h.D., R.D.N., assistant professor at the ...
Water being a relatively polar compound will tend to be miscible with liquids of high polarity such as ethanol and acetone, whereas compounds with low polarity will tend to be immiscible and poorly soluble such as with hydrocarbons. As a gas, water vapor is completely miscible with air.
