MgO melts at a much higher temperature (2852 degrees Celsius) than NaF because Mg2+ is more positively charged than Na+ & O2- ion is smaller than the F-ion. report this answer.
Lithium fluoride, the lithium salt of hydrofluoric acid, may be used as an adjuvant in antibiotic therapy. Lithium fluoride is useful for the development of nanostructures and nanolayers.rticles. Determination of Water Content in Lithium fluoride Using Karl Fischer Titration. Adherent water in salts can be easily determined. It is best to choose a working medium which will prevent the salt from dissolving, e.g. a Methanol-Chloroform mixture with an excess of Chloroform.
Lithium bromide, or LiBr is a chemical compound of lithium and bromine.ithium bromide is used in air-conditioning systems as desiccant. Lithium bromide is used as a salt in absorption chilling along with water (see absorption refrigerator). Otherwise the salt is useful as a reagent in organic synthesis. For example it reversibly forms adducts with some pharmaceuticals.
