The dissociation constants (pK 1⁎ and pK 2⁎ ) for methionine have been measured in artificial seawater as a function of salinity (S=5 to 35) and temperature (5 to 45 °C). The seawater pK 2⁎ values were lower than the values in NaCl at the same ionic strength while the pK 1⁎ values in seawater were lower only at S=35. In an attempt to understand these...
Potentiometric measurements of the stoichiometric constants on the seawater pH scale for the dissociation of carbonic acid in seawater (K 1⁎ =[H + ][HCO 3− ]/[CO 2 ] and K 2⁎ =[H + ][CO 32− ]/[HCO 3− ]) have been made as a function of salinity (1 to 50) and temperature (0 to 50 °C). The results have been fitted...
