Calculation of the Effect of Pressure upon Ionic Equilibria in Pure Water and in Salt Solutions.

A Comparison of the Stable Oxygen and Carbon Isotope Composition of Early Cretaceous and Late Jurassic Carbonates from DSDP Sites 105 and 367

“…The higher temperatures associated with a greater sediment thickness may also be significant. Owen and Brinkley (1941) conclude that an increase in temperature decreases the effect of pressure on the solubility of weak electrolytes, but the increase in the rate of chemical reactions associated with higher temperatures may offset this. Perhaps more significantly, higher temperatures increase the rate of diffusion of ions.…”

Calcium carbonate and the in situ pH

“…They used these coefficients to calculate the effect of depth on the in situ pH. REVELLE and FAIRDRIDGE (1957) used an equation similar to (I) to calculate the change in the solubility product of calcium carbonate with depth from the thermodynamic data of OWEN and BRINKLEY (1941). They predicted an increase in the solubility produzt with depth.…”

The Partial Molal Volumes of Ions in Seawater1

“…The partial molal volumes3 of salts in seawater, V*'O( salt)sw, are of particular interest in oceanography because they can be used to calculate the effect of pressure on ionic equilibrium (Owen and Brinkley 1941) ; they are important in developing better correlations of density, salinity, and conductance ( Wirth 1940a, Duedall, Conners, and Weyl, unpublished); and, as shown later in this paper, they may be useful in understanding ion complex formation.…”

“…The results can also be applied to the elucidation of ion-ion complex formation and ion-water interactions in the ionic medium, seawater. Table 1 gives the partial molal volume of salts in seawater as determined by Duedall and Weyl ( 1967), Owen and Brinkley ( 1941. ) Wirth (1937Wirth ( , 1940b and quoted by Owen and Brinkley (1941) assuming 0.725 m NaCl is equivalent to 35.1%, salinity seawater.…”
