Solubility occurs under dynamic equilibrium, which means that solubility results from the simultaneous and opposing processes of dissolution and phase joining (e.g. precipitation of solids). The solubility equilibrium occurs when the two processes proceed at equal and opposite rates. The term solubility is also … See more In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. See more Solubility is defined for specific phases. For example, the solubility of aragonite and calcite in water are expected to differ, even though they are both See more A popular aphorism used for predicting solubility is "like dissolves like" also expressed in the Latin language as "Similia similibus solventur". This statement indicates that a solute will dissolve best in a solvent that has a similar chemical structure to … See more The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. Any of the several ways of expressing … See more The extent of solubility ranges widely, from infinitely soluble (without limit, i. e. miscible ) 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 … See more Henry's law is used to quantify the solubility of gases in solvents. The solubility of a gas in a solvent is directly proportional to the partial pressure of that gas above the solvent. This relationship is similar to Raoult's law and can be written as: See more Dissolution is not an instantaneous process. The rate of solubilization (in kg/s) is related to the solubility product and the surface area of the material. The speed at which a solid dissolves may depend on its crystallinity or lack thereof in the case of amorphous solids … See more WebMay 8, 2024 · A drug is considered highly soluble if its highest dose strength is soluble in less than 250 mL of water, as tested over a pH range of 1–7.5. A drug is considered high permeable if the oral absorption compares favorably (i.e., higher than 90%) to an intravenous injection of the drug.
