Study of non ideality of various aqueous sodium chloride solutions by vapor pressures measurements and correlation of experimental results by Fitter's method

This article reports experimental vapor pressures of water-NaCl solutions covering the whole miscibility range from 255K to 363K depending on solution. The used apparatus is a static device for pure compounds which has been modified in order to study mixtures. This static apparatus permits to measure vapor pressures from 0.5 Pa to 200 000 Pa. Comparisons between experimental and literature data, experimental and calculated values using Fitter's model indicate a good agreement (relative accuracy < 1% in the whole pressure range).
