Abstract
Reaction volumes ΔVo at infinite dilution and 25°C are obtained by use of a Hashitani dilatometer for protonic ionizations of buffering agents. Combined with recent finding by Hamann that the pressure dependence of the activity coefficient can be estimated by the limiting Debye-Hueckel law even at high ionic strength, one can predict the pH and pOH for these buffer solutions at high pressure.
