Solubility is the maximal quantity that a substance can dissolve as a solute in a host solvent, forming a saturated solution. Any additional quantity occurs as a precipitate and results in a suspension of particles. Solubility is expressed in terms of concentration units for a given temperature and pressure.
Solubility is an essential concept needed in many areas of geochemistry to describe the ability of gas es (g), liquid s (l), or solid s (s) to dissolve in substances. The resulting solutions are homogeneous mixtures of two or more substances, where the solvent is typically, although not necessarily, one of high mole fraction and the solute of lower mole fractions. Examples include the dissolution of sodium chloride (halite) in water, or of water in magmas. In contrast to miscibility where substances can mix in all proportions (e.g., water and ethanol), solubility pertains to the maximal quantity that can be accomodated by the host solvent. This quantity is...
