摘要：
The water activities of aqueous salt solutions have been used to determine the salt-water and ion-water interactions. The relations (aw/Cw)=f(m)(aw- water activity, cw- water concentration, m - molality) are linear for many 1:1 salts, and their slopes may serve as a convenient measure of the salt-water interactions. The ionic contributions to the overall effect have been estimated assuming that the NH^ cations do not affect the water structure and its activity. © R. Oldenbourg Verlag
