Abstract

Solubility data of the conversion system 2NH4+ - 2Na+ - S2O82- - SO42- - H2O at 20 °C and 30 °C for the partial pseudoternary systems Na2S2O8-(NH4)2SO4-H2O, (NH4)2S2O8-Na2SO4-H2O, Na2S2O8-NaNH4SO4-H2O and (NH4)2S2O8-NaNH4SO4-H2O have been correlated using the relative activity coefficient expansion of the crystallizing component. The obtained correlation equations have been used for the calculation of mean activity coefficients of ammonium and sodium peroxodisulfates in their saturated solutions of the mentioned pseudoternary systems.
