Disodium helide (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 prediction algorithm and then synthesised in 2016.
Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate ( anhydrous) is a white crystalline solid having a formula variously given as NaAlO 2, NaAl (OH) 4 ( hydrated ), [3] Na 2 O·Al 2 O 3, or Na 2 Al 2 O 4.
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).

Infobox references. Sodium bis (2-methoxyethoxy)aluminium hydride ( SMEAH; [1] trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a red ucing al uminium compound. It is used predominantly as a reducing agent in organic synthesis.
2 Al + 2 NaOH + 2 H 2 O → 2 NaAlO 2 + 3 H 2. Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO 2, Na 3 AlO 3, Na[Al(OH) 4], Na 2 O·Al 2 O 3 ...
Activation of the H 2 receptor results in the following physiological responses: Stimulation of gastric acid secretion (Target of anti-histaminergics (H 2 receptors) for peptic ulcer disease and GERD) Smooth muscle relaxation (Experimental histamine H 2 receptor agonist used for asthma and COPD)
Na 2 [PtCl 6] + 2 NH 4 Cl → (NH 4) 2 [PtCl 6] + 2 NaCl 3 (NH 4) 2 [PtCl 6] → 3 Pt + 2 N 2 + 2 NH 4 Cl + 16 HCl. This compound also reacts with a base, such as sodium hydroxide, producing [Pt(OH) 6] −2 ion. Applications. A 1.2 M solution of sodium hexachloroplatinate in D 2 O is the most commonly chosen reference compound for chemical ...
Sodium percarbonate, or sodium carbonate peroxide is a chemical substance with formula Na 2 H 3 CO 6. It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na 2 CO 3 · 3 H 2 O 2. It is a colorless, crystalline, hygroscopic and water-soluble ...
Sodium hexafluoroaluminate is an inorganic compound with formula Na 3 Al F 6. This white solid, discovered in 1799 by Peder Christian Abildgaard (1740–1801), [4] [5] occurs naturally as the mineral cryolite and is used extensively in the industrial production of aluminium.
