Chemistry. A substance identified primarily by an EC or list number may be linked with more than one CAS number, or with CAS numbers that have been deleted. [5] This compound is generally regarded as stable, since at room temperature it decomposes only slowly. Zinc arsenide and sodium arsenide are suitable precursors:[10]. [citation needed], It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. 26 Feb. ash3 lewis structure. [14], Reactions of arsine with the halogens (fluorine and chlorine) or some of their compounds, such as nitrogen trichloride, are extremely dangerous and can result in explosions.[6]. Molar Mass: 77.9454. With this apparatus, arsine is obtained by applying vacuum to the gas cylinder valve outlet. See Answer. The acidic properties of the As–H bond are often exploited. A characteristic test for arsenic involves the reaction of AsH3 with Ag+, called the Gutzeit test for arsenic. In the Gutzeit test, AsH3 is generated by reduction of aqueous arsenic compounds, typically arsenites, with Zn in the presence of H2SO4. On the other hand, the appearance of a black mirror deposit in the cool part of the equipment indicates the presence of antimony (the highly unstable SbH3 decomposes even at low temperatures). [4] Despite its lethality, it finds some applications in the semiconductor industry and for the synthesis of organoarsenic compounds. Arsine (AsH 3), a colourless poisonous gas composed of arsenic and hydrogen, is another familiar arsenic compound. . 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.
