Volumetric properties of aqueous electrolytes at high temperature. II. B(OH)3 and B(OH)3-NaB(OH)4-NaOH mixtures up to 523 K

The densities of boric acid aqueous solutions and sodium hydroxide-sodium borate mixtures were measured as a function of concentration, between 375 and 523 K at pressures close to saturation. The partial molar volumes of boric acid were obtained and it was found that they are almost independent of t...
