Paper Title:
Physicochemical Transport Properties of Aqueous Sodium Metaborate Solutions for Sodium Borohydride Hydrogen Generation and Storage and Fuel Cell Applications
  Abstract

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.
