Abstract: The constant-volume piezometer method is used to determine the density of aqueous solutions of sodium sulfate in the temperature range from $291$ to $573$ K and in the ranges of pressures from $2$ to $40$ MPa and concentrations from $0.088$ to $1.116$ mol/kg $\mathrm{H}_2\mathrm{O}$. In view of the available literature data, an equation is constructed describing the specific volumes of solution. Limiting partial molar volumes of electrolyte are calculated.
