摘要：

Electrical conductance measurements have been made at various temperatures and at concentrations from ca. 0.00005 to ca. 0.01 M in aqueous solutions of MgSO4, CaSO4, CoSO4 and NiSO4 at pressures up to 2000 atm. The data have been analyzed with the Fernandez-Prini modification of the Fuoss-Hsia conductance equation to obtain the molal dissociation constants Km at each pressure. The results for V°, obtained from the pressure dependence of Km,are compared with other experimental data and with values calculated from acoustically derived multistate dissociation models. © 1979 Plenum Publishing Corporation.
