Formation of arsine
WebArsenic itself is stable in dry air, but in moist air it tends to become coated with a black oxide. Sublimed arsenic vapour readily burns in air to form arsenious oxide. The free element is essentially unaffected by water, bases, or nonoxidizing acids, but it can be oxidized by nitric acid to the +5 state. WebNov 30, 2024 · A serious drawback to arsine synthesis through the reduction of arsenic is the formation of fine-particle precipitate (0.46 g/Ah in the case of electrolysis in 1 M K 2 HPO 4 ), which contains not only solid (AsH 2) n hydrides but also elemental arsenic particles resulting from comminution of the cathode.
