Abstract:

Present work explores the feasibility of using mixed saturated salt solutions to provide additional solutions of known water activity (aw). The mixed saturated salt solutions studied were: K2SO4‐KNO3, K2SO4‐MgSO4, KCl‐KNO3, NaCl‐KCl and NaCl‐NaNO3. The aw of the ternary saturated salt mixtures was predicted using a theoretical model of the thermodynamic properties of mixed aqueous electrolyte solutions. Prediction of aw compared very well with experimental determinations. Copyright © 1988, Wiley Blackwell. All rights reserved
