Volumetric and transport properties of aqueous sulphuric acid

摘要

Molecular conductance lambda(m), viscosity eta and density rho of sulphuric acid at different concentrations in dilute aqueous solution were measured at 293K. The conductance data were used to calculate the value of the ionic association constant. The experimental values of viscosity and density were Used to calculate the A and B coefficients of the Jone-Dole equation and the apparent molar volume Phi(nu). The behaviour of these parameters suggests that the ion-solvent interactions in the dilute aqueous sulphuric acid and SO42- ion acts as structure maker'. The results were utilized for the applicability of modified Jone-Dole and Staurding equations.
