Prediction and Measurement of the Water Activity of Selected Saturated Salt Solutions at 5°C and 10°C

A theoretical approach, based on the thermodynamic properties of strong electrolyte aqueous solutions, was used to calculate the aw at 5°C and 10°C of selected saturated salt solutions frequently used as standards in the range of microbial growth. The results agreed very well with experimental measu...

The results agreed very well with experimental measurements at both temperatures for most salts studied, which included NaBr, NaCl, SrC12, (NH4)2SO4, KCl, BaCl2, and K2SO4.
