Vapour pressures of H₂ ¹⁶O and H₂ ¹⁸O, and saturated aqueous solutions of KC1 from T = 298 K to T = 318 K by the isoteniscopic method

Vapour pressures of normal water, water enriched by the heavy isotope of oxygen H₂ ¹⁸O, and saturated aqueous solutions of KC1 were determined in the temperature range (298 to 318) K by the isoteniscopic method and compared with the literature data. Water activities, osmotic coefficients, vapour pressure lowerings, boiling point elevations, and molar enthalpies of vaporization at the saturation point of potassium chloride were evaluated from the measured vapour pressures.
