A very detailed, balanced and informative account about the history of EXAFS (originally called Kossel's structures) is given by R. Stumm von Bordwehr. [5] A more modern and accurate account of the history of XAFS (EXAFS and XANES) is given by the leader of the group that developed the modern version of EXAFS in an award lecture by Edward A. Stern.
Lithium nitrate is an inorganic compound with the formula LiNO 3. It is the lithium salt of nitric acid (an alkali metal nitrate). The salt is deliquescent, absorbing water to form the hydrated form, lithium nitrate trihydrate. Its eutectics are of interest for heat transfer fluids. [2] It is made by treating lithium carbonate or lithium ...

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 precipitate.
A study was conducted in Korea to experimentally determine the most effective dose and performance of lithium nitrite corrosion inhibitors. This experiment employed the molar ratio of nitrite ions to chloride ions (NO 2 − /Cl −) as a test parameter. This study concluded that a lithium nitrite dosage of 0.6 in the nitrite-chloride ion molar ...
It can be prepared by metathesis reaction between sodium azide and lithium nitrate or lithium sulfate solutions: NaN 3 + LiNO 3 → LiN 3 + NaNO 3 2 NaN 3 + Li 2 SO 4 → 2 LiN 3 + Na 2 SO 4 [3] It can also be prepared by reacting lithium sulfate with barium azide. Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4 [2]
Ball-and-stick model of the bis(12-crown-4)lithium cation. Like other crown ethers, 12-crown-4 complexes with alkali metal cations. The cavity diameter of 1.2-1.5 Å gives it a high selectivity towards the lithium cation (ionic diameter 1.36 Å) [2] Its point group is S 4. The dipole moment of 12-crown-4 varies with solvent and temperature.
Pentaamminenitritocobalt(III) chloride is an inorganic compound with the molecular formula [Co(NH 3) 5 (NO 2)]Cl 2. It is an orange solid that is soluble in water. The compound has been of academic interest as a source of the transition metal nitrite complex [Co(NH 3) 5 (NO 2)] 2+.
