The density, viscosity, and surface tension of aqueous solutions of sodium sulfite and sodium sulfite + sucrose were measured at temperatures from 25 to 40 degrees C. The concentration ranges were 0-0.5 mol . dm(-3) for sodium sulfite and 0-171 g . dm(-3) for sucrose. The experimental values were correlated with the concentration of sucrose. The maximum deviation was always less than 0.5%.
