Reaction of gallium arsenide with concentrated acids: formation of …

Arsine (IUPAC name: arsane) is an inorganic compound with the formula AsH3. This flammable, pyrophoric, and highly toxic pnictogen hydride gas is one of the simplest compounds of arsenic. Despite its lethality, it finds some applications in the semiconductor industry and for the synthesis of organoarsenic … See more At its standard state, arsine is a colorless, denser-than-air gas that is slightly soluble in water (20% at 20 °C) and in many organic solvents as well. Whereas arsine itself is odorless, owing to its oxidation by air, it is possible to smell a … See more The understanding of the chemical properties of AsH3 is well developed and can be anticipated based on an average of the behavior of See more AsH3 is also well known in forensic science because it is a chemical intermediate in the detection of arsenic poisoning. The old (but extremely sensitive) Marsh test generates AsH3 in the presence of arsenic. This procedure, published in 1836 by See more • Cacodylic acid • Cacodyl oxide • Devarda's alloy, also used to produce arsine in the lab • List of highly toxic gases • Marsh test, first used to analyze AsH3 See more AsH3 is generally prepared by the reaction of As sources with H equivalents. 4 AsCl3 + 3 NaBH4 → 4 AsH3 + 3 NaCl + 3 BCl3 As reported in 1775, Carl Scheele reduced arsenic(III) oxide with zinc in the presence of acid. This … See more Microelectronics applications AsH3 is used in the synthesis of semiconducting materials related to microelectronics and solid-state lasers. Related to See more The toxicity of arsine is distinct from that of other arsenic compounds. The main route of exposure is by inhalation, although poisoning after skin … See more WebIn the fabrication of semiconductors, one step is the formation of additional gallium arsenide (GaAs) on the surface of a GaAs wafer. To accomplish this, gaseous tri- methyl gallium (TMG) and arsine flow in a carrier gas (usually hydrogen) over the solid and react on the solid surface at a temperature of 900K to produce the solid GaAs and long term care fort mcmurrayWebNatural, low-temperature biological reactions involving microbes also release arsenic into the atmosphere. Microbes acting on arsenic in soils and sediments generate arsine gas or other volatile arsenic compounds. Arsine reacts with oxygen in the air and is converted back to non-volatile forms of arsenic, which settle back to the ground. long term care for women
