THE VAPOR-PRESSURES OF SATURATED AQUEOUS-SOLUTIONS OF SODIUM-CHLORIDE, SODIUM-BROMIDE, SODIUM-NITRATE, SODIUM-NITRITE, POTASSIUM IODATE, AND RUBIDIUM CHLORIDE AT TEMPERATURES FROM 227 K TO 323 K

The vapour pressures of saturated aqueous solutions of NaCl, NaBr, NaN O3, NaNO2, KIO3, and RbCl were determined in the temperature range T = (278 to 323)K using an electronic hygrometer with an electrolyte sens or and compared with the literature data, which are available only for the first four salts. These vapour pressures serve to evaluate the wa ter activities, osmotic coefficients, and molar enthalpies of vaporiza tion and solution at saturation. (C) 1998 Academic Press Limited.
