Abstract

The conductivity and viscosity of aqueous solutions of NaBO₂ were measured as a function of concentration at 25°C. Conductivity data was analyzed with various Kohlrausch correlations and the limiting molar conductivity of the BO₂^- ion at infinite dilution was estimated to be of 30.59 S.cm²/mol. From this value, the mobility, diffusion coefficients and transference number for the BO₂ ^- ion were calculated as 3.17×10^-4 cm ²/s.V, 8.14×10^-6 cm²/s, and 0.379 respectively. Ion-solvent and ion-ion interactions were studied with Jones-Dole type correlations, which were employed to analyze the viscosity data. A value of -0.4660 1/M was estimated for the BO₂^- B^- coefficient.
