N. Hubert et al., AQUEOUS-SOLUTION OF SODIUM-SULFATE - DETERMINATION OF THE DISSOLUTIONENTHALPY AT 25, 27.5 AND 45-DEGREES-C, Thermochimica acta, 259(1), 1995, pp. 41-48
The dissolution enthalpy of sodium sulfate in water was measured until
saturation at 24.4, 27.5 and 44.3 degrees C using a C80D differential
calorimeter (Setaram). The experimental data were fitted using Pitzer
's ion interaction model and the value of the dissolution enthalpy per
mole of salt at infinite dilution was found at each temperature, by t
reating (Delta(diss)H)(infinity) as an adjustable parameter.
