摘要：

Vapour pressures of saturated aqueous solutions of Na2SO4, CaBr2, FeCl3, Zn(NO3)(2), Ca(NO3)(2), and LiNO3 were determined in the temperature range from 278 K to 323 K using an electronic hygrometer with an electrolyte sensor and compared with literature data. Water activities, osmotic coefficients, and molar enthalpies of vapourization and solution at saturation point were evaluated from the determined vapour pressures. (C) 2002 Elsevier Science Ltd.
