Abstract

The stoichiometric dissociation constants of boric acid in seawater at S = 35 have been determined from 0 to 55°C. The constants were determined from electromotive force measurements made with the cell, Pt|H2 (g, 1 atm)|;borax in synthetic seawater|;AgCl, Ag. The results are discussed in terms of "total" hydrogen ion scale. Our results are in excellent agreement (±0.0004 in ln K*) with the measurements of Dickson (1990a). This study demonstrates that the measurements made by Dickson (1990a) are more reliable than the earlier measurements (Buch, 1933; Lyman, 1956; Hansson, 1973b) and should be used in all future studies of the carbonate system in seawater.
