Solubility


Noun

1. The property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent. The solubility of a substance fundamentally depends on the physical and chemical properties of the used solute and solvent as well as on temperature, pressure and the pH of the solution. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration, where adding more solute does not increase the concentration of the solution and begin to precipitate the excess amount of solute. (wikipedia.org)

2. The condition of being soluble. (wiktionary.org)

3. (Chemistry) The amount of a substance that will dissolve in a given amount of a solvent, to give a saturated solution, under specified conditions. (wiktionary.org)

4. The quantity of a particular substance that can dissolve in a particular solvent (yielding a saturated solution). (biology-online.org)

5. (Botany) The tendency to separate readily into parts by spurious articulations, as the pods of tick trefoil. (biology-online.org)

Word origin: From Middle French soluble, from Late Latin solubilis “that may be loosened or dissolved,” from stem of Latin solvere “loosen, dissolve” + –ity
