Influence of pressure on chemical equilibria in aqueous systems - With particular reference to seawater

The influence of pressure on chemical equilibria in aqueous solutions and t he parameters that influence such equilibria are reviewed in this work. Par ticular emphasis is given to equilibria in seawater, including mineral diss olution, weak acid dissociation and metal ion complexation. Intended perspe ctives include the capabilities of predictive models to describe chemical e quilibria in low temperature geochemical systems and the extent to which pr edictive models are constrained by direct observations. In context of the i mportance of pressure as a key variable controlling the pathways and fate o f environmental chemicals, a need for further direct observations of chemic al equilibria at high pressure, under conditions which are often challengin g to the experimentalist, is evident.
