Summary

The adiabatic compressibility of NaCl, NaBr and NaI water solutions has been determined by measuring the sound velocity as a function of both concentration and temperature. A simple model has been employed to interpret the data in terms of size of hydration shells. Reasonably good agreement has been found with neutron and X-ray diffraction results.

Riassunto

La compressibilità adiabatica delle soluzioni acquose di NaCl, NaBr ed NaI è stata misurata determinando la velocità del suono in funzione di temperatura e concentrazione. Per interpretare i dati è stato impiegato un modello semplice che tiene conto delle sfere di idratazione degli ioni. Tale modello risulta in soddisfacente accordo con i dati ricavati da un esperimento di diffrazione di raggi X e neutroni.

Резюме

Определяется адиабатическая сжимаемость водньх растворов NaCl, NaBr и NaI, используя измерения зависимостей скорости звука от концентрации и температурь. Предлагается простая модель для интерпретации данньих в терминах размера сферьі гидратации. Получется хошее согласие с результатами дифракции нейтронов и рентгеновских лучей.
