摘要

The conductivity and viscosity of aqueous solutions of NaBO_2 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 (BO_2)~- - ion at infinite dilution was estimated to be of 30.59 S.cm~2/mol. From this value, the mobility, diffusion coefficients and transference number for the (BO_2)~- - ion were calculated as 3.17×10~(-4) cm~2/s.V, 8.14×10~(-6) cm~2/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 (BO_2)~- B~- coefficient.
