Solubility

Abstract

The concept of solubility is essential in geochemistry for describing the maximal quantity of a substance that can be dissolved in solutions. It often becomes a starting talking point for understanding whether solutions are homogeneous or prone to bear particular matter. Preditions of solubility often require a distinct thermodynamic treatment of the solute and the solvent that can be built in different modeling frameworks. Equations of states or more empirical sets of equations can be used to effectively predict solubility over a range of conditions relevant to the solvent. Examples include salinity and pH of water, partial pressures of gases, as well as pressure and temperature of water and melts. The concept of solubility thus applies to diverse aspects of Earth Sciences and enables a means for formulating predictive models on mass transport in nature.
