Vapor Pressure of Saturated Aqueous Solutions of Potassium Sulfate from 310 K to 345 K

الملخص EN

The experimental evaluation of the vapor pressure of saturated aqueous solutions of potassium sulfate was carried out in the range of temperatures 310 K≤T≤345 K.

The experimental data were used to determine the corresponding values of the water activity in such solutions.

The analytical expressions as a function of temperature of both, vapor pressure and water activity, were obtained from the correlation of the experimental results.

The vapor pressure expression was also extrapolated to a different temperature range in order to make a comparison with the results obtained by other authors.
