Solubility is the physical property referring to the ability of a given substance, the solute, to dissolve in a solvent. It is
measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called
a saturated solution. Certain liquids are soluble in all proportions with a given solvent, such as ethanol in water. This
property is known as miscibility. Under certain conditions the equilibrium solubility can be exceeded to give a so-called
supersaturated solution, which is metastable.
In a solution, the solvent is generally a liquid, which can be a pure substance or a mixture. The species that dissolves, the
solute, can be a gas, another liquid, or a solid. Solubilities range widely, from infinitely soluble such as ethanol in water, to
poorly soluble, such as silver chloride in water. The term insoluble is often applied to poorly soluble compounds, although
in some cases insolubility means that a compound is very poorly soluble.
