Talk:Critical relative humidity

Can one assume that a small amount of a salt that is damp (not wet and completely saturated, and not dried) inside a sealed glass container will act as a buffer^* to maintain a relative humidty RH the same as the Critical Relative Humidity (provided the container and air inside is at the temperature the CRH is specified) ? *buffer=device that will over time absorb water vapor or release water vapor --Teeteetee 16:45, 28 November 2006 (UTC)

• Yes, the above is true. The procedure above is used to detemine the CRH for salts and saltmixtures (in fertiliser industry). The glass container has in this case been equipped with a hygrometer sensor. This property of salts is also used in laboratories to create an atmosphere with constant relative humidity (when one cannot afford a climate chamber apparatus!).

I notice Sodium chloride (table salt) is not included, if anyone knows its CRH it might improve the article
