Infobox references. Lithium sulfide is the inorganic compound with the formula Li 2 S. It crystallizes in the antifluorite motif, described as the salt (Li +) 2 S 2−. It forms a solid yellow-white deliquescent powder. In air, it easily hydrolyses to release foul smelling hydrogen sulfide gas.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to ...
Lithium sulfite. [Li+]. [O-]S (O)=O. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Lithium sulfite, or lithium sulphite, is an ionic compound with the formula Li 2 SO 3. [1]
Lithium oxide (Li. 2 O) or lithia is an inorganic chemical compound. It is a white solid. Although not specifically important, many materials are assessed on the basis of their Li 2 O content. For example, the Li 2 O content of the principal lithium mineral spodumene (LiAlSi 2 O 6) is 8.03%. [2]
Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline mass, in flake form, or as a fused solid.
In common phase II form, Lithium sulfate has a sphenoidal monoclinic crystal system that has edge lengths of a = 8.23Å b = 4.95Å c = 8.47Å β = 107.98°. When lithium sulfate is heated passed 130 °C it changes to a water free state but retains its crystal structure. It is not until 575 °C when there is a transformation from phase II to ...
Lithium (from Ancient Greek λίθος (líthos) 'stone'; symbol Li and atomic number 3) is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert ...
Arsenide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). In chemistry, an arsenide is a compound of arsenic with a less electronegative element or elements. Many metals form binary compounds containing arsenic, and these are called arsenides.
