The conductivity and viscosity of aqueous solutions of NaBO2 were measured as a function of concentration at 25oC. 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 3.17x10-4 cm2/s.V, 8.14x10-6 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.
