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?

| Peritoneal dialysis is not an option because it fails to clear solutes faster than they appear. AQP9 is a member of the aquaglyceroporin family of channels that facilitates bidirectional movement of small neutral solutes such as glycerol and urea (Agre and Kozono 2003). There may be differences in the mineral and bacterial composition of the various tap, distilled, spring, and bottled water but unless these solutions contain solutes that are impermeable to the cell membrane, these apparent "differences" would not influence the distribution of total body water. |
