The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



the ability of one substance to combine with another and form a homogeneous, thermodynamically stable system of variable composition made up of two or more components. These systems are formed upon interaction of gases with liquids, liquids with liquids, and other similar combinations. The ratios of the components to one another may be either arbitrary or restricted within certain limits. In the latter case, the solubility is said to be limited.

The solubility of a substance under given conditions is determined from the substance’s concentration in a saturated solution. The solubility of various substances in a specific solvent depends on external conditions, mainly on the temperature and pressure. The effect of pressure on solubility is most pronounced with gases. A change in external conditions affects solubility in accordance with the principle of equilibrium shift (see LECHÂTELiER’S PRINCIPLE). Solubility charts of various substances have been compiled for the most important solvents. Such charts either express solubility as a function of external conditions or simply list the solubility under standard conditions.

Water sorption and solubility of each specimen was calculated by weighting the samples before and after immersion in water for 15 days and desiccation.
A capillary column is brought to equilibrium with a plateau concentration of the solvent and then an additional pulse of the solvent is introduced and the resulting peak is numerically analyzed for the solubility and diffusivity.
Maximum solubility by selfdispersion of milk powder can only be obtained with powders having bulk densities of less than 0.4 g/ml [16].
In another research about the struvite crystallization it was concluded that 30 degrees Celsius is the temperature of maximum struvite solubility. The higher temperatures might affect the struvite structure and this transition which is accompanied by phase change would affect the struvite solubility to high extent (Burns, J.R.
