Solubilities and vapour pressures of saturated aqueous solutions of sodium peroxydisulfate and potassium peroxydisulfate
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. (C) 2001 Academic Press.
