Abstract
The speciation of Cl-, OH- and SO42- in synthetic sea water has been s tudied by potentiometric measurements (pH-metric and ISE-Na methods)an d by literature data analysis, using a well tested complex formation m odel. Stability constants, together with distribution of hypothesised species in synthetic sea water, as a function of temperature and salin ity, are reported. The speciation model proposed in this work is discu ssed on the basis of chemical and statistical considerations. Comparis on with some literature sea water models is given.
