Influence of Pressure on Chemical Equilibria
Aqueous Systems - with Particular Reference to Seawater
Prepared for publication by R.
H. Byrne and S. H.
Synopsis: The influence of pressure
on chemical equilibria in aqueous solutions and the parameters that
influence such equilibria are reviewed in this work. Particular emphasis
is given to equilibria in seawater, including mineral dissolution, weak
acid dissociation and metal ion complexation. Intended perspectives
include the capabilities of predictive models to describe chemical equilibria
in low temperature geochemical systems and the extent to which predictive
models are constrained by direct observations. In context of the importance
of pressure as a key variable controlling the pathways and fate of environmental
chemicals, a need for further direct observations of chemical equilibria
at high pressure, under conditions which are often challenging to the
experimentalist, is evident.
