Apparatus Determining Water Activity with Isopiestic Method and Measurement of Water Activity

Abstract:

A new apparatus determining water activity using isopiestic method was developed. The water activities of the systems of LiCl−H₂O, NaCl−H₂O and KCl−H₂O at 298.15 K were measured using isopiestic method. Compared with the literature, the results of measurement are in good agreement with the literature, and the apparatus reliability was verified.
