Influence of Fructose in the Diffusion of Sodium Borate in Aqueous Solutions at 298.15 K

Mutual diffusion coefficients have been measured at 298.15 K for aqueous systems containing sodium borate at concentration 0.100 mol dm⁻³ and fructose at various concentrations (from 0.001 to 0.100 mol dm⁻³), by using a conductimetric Lobo’s cell. From these data, we can say that the presence of fructose affects the diffusion of sodium borate. Two effects can explain this behavior: the ionic association and the salting-out effect.
