Roland Beyer, Michael Steiger (2002): Vapour pressure measurements and thermodynamic properties of aqueous solutions of sodium acetate.- In: The Journal of Chemical Thermodynamics, 34, 7, pp. 1057-1071, doi: 10.1006/jcht.2002.0974

Abstract

The vapour pressure of (sodium acetate + water) was measured in the temperature range 278.15 K to 308.15 K and in the molality range 0.65 mol · kg⁻¹to 6.47 mol · kg⁻¹with a static method. Water activities and osmotic coefficients were calculated. A comprehensive search of the available literature for the relevant thermodynamic data of the investigated system was carried out. The most reliable values were used in a least-squares treatment using the Pitzer formalism in the temperature range 255 K to 398 K and the molality range 0 mol · kg⁻¹to 25 mol · kg⁻¹.
