Saturated salts for humidity control
Webblong to wait before use. If the solution is saturated with an excess of salts at boiling, a solid mass will result when it cools; this wastes salts and is difficult to remedy. The temperature of the system must be kept constant with a well-controlled water-bath. However, certain salts, such as NaCl, are quite consistent over a wide Webb5.4. Use of Saturated Salt Solutions When saturated salt solutions are employed for humidity control, experience has shown that certain precautions must be observed in order that the theoretical values may be used without the need of measurement. It is necessary to enclose the satu- rated salt solution in a sealed chamber.
