In its initial application, Bousfield studied the water vapor pressures required to begin hydrating and then dissolving initially dry samples of NaCl, KCl, and KNO , thus yielding the vapor pressure and consequently the water activities of their satu- rated solutions at 291  K. Solutions of LiCl(aq) were also present during the experiments and were used as standard solutions for determining the vapor pressure of water. Bous- field’s apparatus consisted of a Hempel desiccator containing a tin stand with four glass dishes to hold the salt samples. The total amount of water in the system was controlled by adding a little water or desiccant to the desiccator’s lid at the start of an experiment. Sinclair [2] recognized the potential of the isopiestic method for determining accurate water vapor pressures of unsaturated aqueous solutions, provided that
