The vapour 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, NaNO₃, NaNO₂, KIO₃, and RbCl were determined in the temperature range T = (278 to 323) K using an electronic hygrometer with an electrolyte sensor and compared with the literature data, which are available only for the first four salts. These vapour pressures serve to evaluate the water activities, osmotic coefficients, and molar enthalpies of vaporization and solution at saturation.
