The hydride reacts with the weak Bronsted acid releasing H 2. Hydrides such as calcium hydride are used as desiccants, i.e. drying agents, to remove trace water from organic solvents. The hydride reacts with water forming hydrogen and hydroxide salt. The dry solvent can then be distilled or vacuum transferred from the "solvent pot".
Copper hydride is also produced by reductive sonication. In this process, hexaaquacopper(II) and hydrogen(•) react to produce copper hydride and oxonium according to the equation: [Cu(H 2 O) 6] 2+ + 3 H • → 1 / n (CuH) n + 2 [H 3 O] + + 4 H 2 O. Hydrogen(•) is obtained in situ from the homolytic sonication of water. Reductive sonication ...
The reaction involves no changes in the oxidation state of the metal and can be viewed as splitting H 2 into hydride (which binds to the metal) and proton (which binds to the base). ML n x+ + base + H 2 ⇌ HML n (x-1)+ + Hbase + Such reaction are assumed to involve the intermediacy of dihydrogen complexes. Bifunctional catalysts activate H 2 ...
Calcium hydride is the chemical compound with the formula CaH 2, an alkaline earth hydride. This grey powder (white if pure, which is rare) reacts vigorously with water, liberating hydrogen gas. CaH 2 is thus used as a drying agent, i.e. a desiccant. [2] CaH 2 is a saline hydride, meaning that its structure is salt-like. The alkali metals and ...
Mercury(II) hydride may be prepared by the reduction of mercury(II) chloride. In this process, mercury(II) chloride and a hydride salt equivalent react to produce mercury(II) hydride according to the following equations, which depend on the stoichiometry of the reaction: 2 HgCl 2 + 2 H − → HgCl 2− 4 + HgH 2 HgCl 2 + 2 H − → HgH 2 + 2 ...
Lithium hydride is an inorganic compound with the formula Li H.This alkali metal hydride is a colorless solid, although commercial samples are grey. Characteristic of a salt-like (ionic) hydride, it has a high melting point, and it is not soluble but reactive with all protic organic solvents.
Sodium hydride is the chemical compound with the empirical formula Na H. This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis . NaH is a saline (salt-like) hydride , composed of Na + and H − ions, in contrast to molecular hydrides such as borane , silane , germane , ammonia , and methane .
Titanium hydride normally refers to the inorganic compound TiH 2 and related nonstoichiometric materials. [1] [2] It is commercially available as a stable grey/black powder, which is used as an additive in the production of Alnico sintered magnets, in the sintering of powdered metals, the production of metal foam, the production of powdered titanium metal and in pyrotechnics.
