  <dc:description>&lt;p&gt;A new method for measuring the solubility of simple salts in water at elevated temperatures involves heating assemblages of salt crystals plus solution vapor at a constant rate in a platinum-lined bomb. The dissolution of the last salt crystal is evidenced by a distinct discontinuity in the pressure-temperature curve. Studies of the solubilities of NaCl and of KC1 in water yielded equations expressing the solubility as functions of temperature, t in °C, at the vapor pressure of the solutions as follows:&lt;/p&gt;&lt;p&gt;weight percent NaCl=26.218+0.0072&lt;i&gt;t&lt;/i&gt;+0.000106&lt;i&gt;t&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt;±0.05 weight percent NaCl&lt;/p&gt;&lt;p&gt;weight percent KCl=27.839+0.0794&lt;i&gt;t&lt;/i&gt;+0.000027&lt;i&gt;t&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt;±0.10 weight percent KCl&lt;/p&gt;&lt;p&gt;The NaCl and KC1 data were measured over the temperature range 148° to 425°C and 148° to 371°C, respectively. However, the equation for NaCl appears to be valid over the range 0° to 800°C, and the KC1 equation appears valid over the range 100° to 450°C.&lt;/p&gt;</dc:description>
