Zero Ionic Strength Data at High Pressure

Zero Ionic Strength Data at High Pressure 

Protolysis constant data can also be calculated from the equations of Bandura and LVov (2006) at elevated pressure. The density of water increases as the pressure increases. As indicated previously, the equations of Bandura and Lvov require that only the temperature and the density at that temperature are known to determine the protolysis constant of water. Since the density is a function of pressure, protolysis constant data can also be derived for conditions of high (or low) pressure. Such data are presented in Table 5.36. 

As seen in Section 5.2, the protolysis constant of water has a rigorous derivation, and its value at 25 °C is log K ° = -13.994 0.014. This constant relates to the 

Others have argued, however, that the protolysis constant of water should be log KJ = —15.74, a value which has some acceptance even though it is derived 

Starkey ef a/. (1986) had proposed the more negative log/iC, having derived the value using water as a solute and a Henry s law standard state despite its solvent environment (Campbell and Waite, 1990). Campbell and Waite examined the relative acidity strength of water with glycerine according to the following reaction
