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...
