Description

Excerpt from A Study of the Vapor Pressure of Aqueous Solutions of Potassium Chloride at 20°c: Dissertation Submitted to the Board of University Studies of the Johns Hopkins University in Conformity With the Requirements for the Degree of Doctor of Philosophy AT 80°c. Ihile continuing the study of the vapor pressure of aqueous solutions by the improved static method devised by Frazer and Lovelace} it was found that the process originally employed for the removal of air from the solutions was unsatisfactory both from the standpoint of completeness and of the time consumed. To overcome these objections it seemed desirable to prepare the solutions in vacuo, i.s., mix the air free constituents in a vacuum, or else boil the solutions untill all air is expelled, sealing the container while filled with steam. On account of the instability of some solutions at boiling temperatures. It was decided to develop the first method mentioned above which is herein later described in detail. The work with solutions thus prepared so nearly air free has revealed the possibility that the former measurements may be unreliable due to traces of air in the solutions. While the statement is made in the reports of former work that no readings of the vapor pressure lowering were made until the vcleod gauge showed a residual air pressure of less than mm after a 24-hour expansion.
