solubilityDegree to which a substance dissolves in a solvent to make a solution (usually expressed as grams of solute per litre of solvent). Solubility of one fluid (liquid or gas) in another may be complete (totally miscible; e.g., methanol and water) or partial (oil and water dissolve only slightly). In general, “like dissolves like” (e.g., aromatic hydrocarbons dissolve in each other but not in water). Some separation methods (absorption, extraction) rely on differences in solubility, expressed as the distribution coefficient (ratio of a material's solubilities in two solvents). Generally, solubilities of solids in liquids increase with temperature and those of gases decrease with temperature and increase with pressure. A solution in which no more solute can be dissolved at a given temperature and pressure is said to be saturated (see saturation). See also Joel Hildebrand. solubility [‚säl·yə′bil·əd·ē] (physical chemistry) The ability of a substance to form a solution with another substance. How to thank TFD for its existence?

| Because the drug isn't water soluble, it's mixed into a solvent called eremophor, which can cause severe allergic reactions and is responsible for many of the treatment's side effects. Because it's water soluble, it simplifies core removal and allows sand and binder to be reused. Haze or whitening also may be due to water soluble or dispersible materials such as dispersants, rheology modifiers, and surfactants that come to the surface. |
