| Résumé : | An electrodeless conductivity cell was employed to investigate the electrical conductivity of concentrated NaCl−H2SO4−H2O solutions particularly at high temperatures. All solutions were measured from 25 to 250 °C at the equilibrium vapor pressures. The maximum measured concentrations of NaCl and H2SO4 were 0.40 and 0.45 m, respectively. At 250 °C and a fixed concentration of H2SO4, the conductivity of NaCl−H2SO4−H2O solutions increases with the increasing concentration of NaCl. Similarly, at 250 °C and a fixed concentration of NaCl, the conductivity of NaCl−H2SO4−H2O solutions increases with the increasing concentration of H2SO4. It was found that the ionic equivalent conductivity of H3O+ is a function of ionic strength at 250 °C and is independent of the solution speciation. |
