摘要/Abstract

摘要： Density, pH, viscosity, conductivity and the Raman spectra of aqueous NaB(OH)₄ solutions precisely measured as functions of concentration at different temperatures (293.15, 298.15, 303.15, 313.15 and 323.15 K) are presented. Polyborate distributions in aqueous NaB(OH)₄ solution were calculated, covering all the concentration range, B(OH)₄^- is the most dominant species, other polyborate anions are less than 5.0%. The volumetric and the transport properties were discussed in detail, both of these properties indicate that B(OH)₄^- behaves as a structure-disordered anion.
