An investigation of the critical liquid-vapor properties of dilute KCl solutions
The three parameters that define the critical point, temperature, pressure, and volume have been experimentally determined by means of filling studies in a platinum-lined system for five KCl solutions ranging from 0.006 to 0.568 m . The platinum-lined vessels were used to overcome the problems with corrosion experienced by earlier workers. The critical temperature ( t c ), pressure ( P c ), and volume ( V c ) were found to fit the equations t c = 374.14   +   16.602 m   +   41.740 m  ± 0.5 ∘ C P c = 220.9   +   135.164 m  +   41.173 m 2   ±   0.5 b a r s V c = 3.155   −   1.373 m   +   0.507 m  ±   0.008 c m 3 − g − 1 "> t c = 374.14 + 16.602 m −−√ + 41.740 m ± 0.5 ∘ C P c = 220.9 + 135.164 m + 41.173 m 2 ± 0.5 b a r s V c = 3.155 − 1.373 m −−√ + 0.507 m ± 0.008 c m 3 − g − 1 tc=374.14 + 16.602m + 41.740m ±0.5∘CPc=220.9 + 135.164m + 41.173m2 ± 0.5barsVc=3.155 − 1.373m + 0.507m ± 0.008cm3−g−1 from infinite dilution to 1.0 m .
