Editing Lithium chloride (section)

===Niche uses===
Lithium chloride is used as a relative humidity standard in the calibration of [[hygrometer]]s.  At {{convert|25|C|F}} a saturated solution (45.8%) of the salt will yield an equilibrium relative humidity of 11.30%. Additionally, lithium chloride can be used as a hygrometer. This deliquescent salt forms a self-solution when exposed to air.  The equilibrium LiCl concentration in the resulting solution is directly related to the relative humidity of the air. The percent relative humidity at {{convert|25|C|F}} can be estimated, with minimal error in the range {{convert|10-30|C}}, from the following first-order equation: RH=107.93-2.11C, where C is solution LiCl concentration, percent by mass.
