Disodium helide. [Na]. [Na]. [He] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Disodium helide [2] (Na 2 He) is a compound of helium and sodium that is stable at high pressures above 113 gigapascals (1,130,000 bar). It was first predicted [3] using the USPEX crystal structure ...
Sodium periodate is an inorganic salt, composed of a sodium cation and the periodate anion.It may also be regarded as the sodium salt of periodic acid.Like many periodates, it can exist in two different forms: sodium metaperiodate (formula NaIO 4) and sodium orthoperiodate (normally Na 2 H 3 IO 6, but sometimes the fully reacted salt Na 5 IO 6).
An electride, [Na(NH 3) 6] + e −, is formed as a reaction intermediate. 2 Na + 2 NH 3 → 2 NaNH 2 + H 2. NaNH 2 is a salt-like material and as such, crystallizes as an infinite polymer. The geometry about sodium is tetrahedral. In ammonia, NaNH 2 forms conductive solutions, consistent with the presence of [Na(NH 3) 6] + and NH − 2 ions. Uses
Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3. Sodium bisulfite in fact is not a real compound, [2] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions. It appears in form of white or yellowish-white crystals ...
Disodium phosphate ( DSP ), or disodium hydrogen phosphate, or sodium phosphate dibasic, is an inorganic compound with the chemical formula Na 2 H P O 4. It is one of several sodium phosphates. The salt is known in anhydrous form as well as hydrates Na2HPO4·nH2O, where n is 2, 7, 8, and 12. All are water-soluble white powders.
Sodium persulfate is the inorganic compound with the formula Na 2 S 2 O 8. It is the sodium salt of peroxydisulfuric acid, H 2 S 2 O 8, an oxidizing agent. It is a white solid that dissolves in water. It is almost non- hygroscopic and has good shelf-life.
Sodium dithionate Na 2 S 2 O 6 is an important compound for inorganic chemistry. It is also known under names disodium dithionate, sodium hyposulfate, and sodium metabisulfate. The sulfur can be considered to be in its +5 oxidation state . It should not be confused with sodium dithionite, Na 2 S 2 O 4, which is a very different compound, and is ...
Sodium pyrosulfate is an inorganic compound with the chemical formula of Na 2 S 2 O 7. [1] It is a colorless salt. [3] It hydrolyses in water to form sodium bisulfate with a chemical formula of NaHSO4 which has a pH of around 1.
