Abstract

Solubilities of sodium peroxydisulfate and potassium peroxydisulfate in water and vapour pressures of saturated solutions were determined as a function of temperature. The vapour pressures served to evaluate the water activities, osmotic coefficients and molar enthalpies of vaporization. The molar enthalpy of solution of sodium peroxydisulfate was determined calorimetrically.
