The hydride, SrH 2, was obtained by Guntz on heating strontium amalgam in a current of hydrogen.
Although at the present time a marvellous improvement has taken place all round in the quality of the carbide produced, the acetylene nearly always contains minute traces of hydrogen, ammonia, sulphuretted hydrogen, phosphuretted hydrogen, silicon hydride, nitrogen and oxygen, and sometimes minute traces of carbon monoxide and dioxide.
The presence of free hydrogen is nearly always accompanied by silicon hydride formed by the combination of the nascent hydrogen with the silicon in the carbide.
It combines with hydrogen to form a hydride.Advertisement
Zirconium hydride, ZrH2, is supposed to be formed when zirconia is heated with magnesium in an atmosphere of hydrogen.
The gas is rapidly absorbed by solutions of the caustic alkalis, with the production of alkaline carbonates (q.v.), and it combines readily with potassium hydride to form potassium formate.
The compounds containing this radical are treated under other headings; the hydride is better known as ethane, the alcohol, C 2 H 5 OH, is the ordinary alcohol of commerce, and the oxide (C 2 H 5) 2 O is ordinary ether.
Buff carried out an inquiry on the compounds of silicon in which they prepared the previously unknown gas, silicon hydride or silicuretted hydrogen.
Hantzsch explains the characteristic reactions of the diazonium compounds ky the assumption that an addition compound is first formed, which breaks down with the elimination of the hydride of the acid radical, and the formation of an unstable syn-diazo compound, which, in its turn, decomposes with evolution of nitrogen (Ber., 18 97, 30, p. 2 54 8; 1898, 31, p. 2053).Advertisement
Strontium hydride behaves similarly.
Merrill, it decomposes when heated, and gives cupric hydride, CuH 21 as a reddish-brown spongy mass, which turns to a chocolate colour on exposure.
Wurtz's first published paper was on hypophosphorous acid (1842), and the continuation of his work on the acids of phosphorus (1845) resulted in the discovery of sulphophosphoric acid and phosphorus oxychloride, as well as of copper hydride.
It phosphoresces in ozone, but not in air, and is nonpoisonous; from its solution in alcoholic potash acids precipitate the hydride P 12 H 6, and when heated it is transformed into the red modification.
By passing the products of the decomposition of calcium phosphide with water over granular calcium chloride, the P 2 H 4 gives a new hydride, P1.2H6 and phosphine, the former being an odourless, canary-yellow, amorphous powder.Advertisement
Some models use alkaline (AAA) batteries, while others use rechargeable batteries (lithium, nickel-cadmium or nickel-metal hydride ).
Toyota's Rav 4 prototype uses a metal hydride to carry hydrogen in solid form.
The basic principle is that certain metals alloys absorb hydrogen to form a metal hydride.

Further, since methane may be regarded as formed b y the conjunction of a methyl group with a hydrogen atom, it may be named " methyl hydride "; similarly ethane is " ethyl hydride," propane, " propyl hydride," and so on.
Siemens and Halske have proposed the addition of oxidizing agents such as free halogens, to prevent the formation of zinc hydride, to which they attribute the formation of zincsponge.
It also combines directly with potassium hydride to form potassium formate (see Formic Acid).
Moissan (Comptes rend., 1902, 134, p. 261) prepared potassium formate by passing a current of carbon monoxide or carbon dioxide over heated potassium hydride, KH+CO 2 = Khco 2 and KH-F2CO = Khco2+C.
