Arsenic tribromide can be prepared by the direct bromination of arsenic powder. Alternatively, arsenic(III) oxide can be used as the precursor in the presence of elemental sulfur: 2 As 2 O 3 + 3 S + 6 Br 2 → 4 AsBr 3 + 3 SO 2. Arsenic tribromide is a highly water soluble crystalline arsenic source for uses compatible with bromides and lower ...
Tribromide is the anion with the chemical formula Br 3 ... Arsenic tribromide, AsBr 3; Berkelium tribromide, BkBr 3; Bismuth tribromide, BiBr 3; Boron tribromide, BBr 3;
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
Arsenic is used as the group 15 element in the III-V semiconductors gallium arsenide, indium arsenide, and aluminium arsenide. [10] The valence electron count of GaAs is the same as a pair of Si atoms, but the band structure is completely different which results in distinct bulk properties. [ 11 ]
Hydrolysis occurs only slowly in water forming arsenic trioxide and hydroiodic acid. The reaction proceeds via formation of arsenous acid which exists in equilibrium with hydroiodic acid. The aqueous solution is highly acidic, pH of 0.1N solution is 1.1. It decomposes to arsenic trioxide, elemental arsenic and iodine when heated in air at 200 °C.
Arsenic trichloride can be prepared by the reaction of arsenic oxide and sulfur monochloride. This method requires simple apparatus and proceeds efficiently: [8] 2 As 2 O 3 + 6 S 2 Cl 2 → 4 AsCl 3 + 3 SO 2 + 9 S. A convenient laboratory method is refluxing arsenic(III) oxide with thionyl chloride: [9] 2 As 2 O 3 + 3 SOCl 2 → 2 AsCl 3 + 3 SO 2

Since Lewis adducts are formed by dative bond between Lewis bases and Lewis acids, the orbital overlap between the Lewis base and σ*(Sb–X) orbital is the source of the acidity. According to Gabbaï et al., NBO analysis of the Sb(C 6 F 5) 3 P(O)Ph 3 adduct indicates a donor-acceptor interaction between lp(O) and σ*(Sb–C 6 F 5). [7] [8]
