Abstract
We consider the effect of dissolved air on the density and the refractive index of liquid water from 0 ¿aC to 50 ¿aC. The density effect is calculated from the best available values of Henry's constants and partial molar volumes for the components of air; the results are in agreement with some previous experimental studies but not others. The refractive-index effect is calculated as a function of wavelength from the same information, plus the refractivities of the atmospheric gases. We also report experimental measurements of the refractive-index effect at both visible and ultraviolet wavelengths; the measured and calculated values are in reasonable agreement. The magnitude of the refractive-index change, while small, is several times larger than a previous estimate in the literature.Citation
