Vapor Pressure of Saturated Aqueous Solutions of Potassium Sulfate from 310 K to 345 K
The experimental evaluationof the vapor pressure of saturated aqueous solutionsof potassiumsulfate wascarried out in the range of temperatures 310K ≤ T ≤ 345K. 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.
