ABSTRACT
The densities of (ammonium, sodium, and potassium) sulfates in ethanol + water solutions were measured in the temperature range of (283.15 to 298.15) K, in saline concentrations from zero to the solubility limit and at atmospheric pressure. The binary and ternary systems were correlated using polynomial expressions, with the selected parameters depending on the composition of the mixtures. Data fitting shows a good agreement with experimental values.
