Physical properties of aqueous solutions of NaHCO3, Na2CO3 and Na2CO3-NaHCO3 in the presence of sucrose and glucose

It has been experimentally determined the density, viscosity and surface tension of NaHCO3 and Na2CO3 aqueous solutions with a concentration of 0.5 mol/L and NaHCO3/Na2CO3 buffer solutions (0.5M-0.5M) in the presence of sucrose or glucose (concentrations between 0 and 175 g/L), in the temperatures interval of 25 to 40 degrees C. The obtained data have been correlated with sucrose or glucose concentration. The parameters that take part in the correlation reactions are provided. Maximum derivations are lower to 0.5% for different properties.
