3 anion can be obtained by, for example, the oxidation of astatine with potassium hypochlorite in a solution of potassium hydroxide. [31] [32] Preparation of lanthanum triastatate La(AtO 3) 3, following the oxidation of astatine by a hot Na 2 S 2 O 8 solution, has been reported. [33] Further oxidation of AtO −
Chemical formula. At Br: Molar mass: 289.904 g/mol Related compounds Other anions. ... Astatine bromide is an interhalogen compound with the chemical formula At Br.
It is created according to the following equation: Br 2 (l) + F 2 (g) → 2 BrF(g) Bromine monofluoride dissociates like this: 3 BrF → Br 2 + BrF 3 Astatine chloride Astatine bromide Astatine iodide. Iodine monofluoride (IF) is unstable and decomposes at 0 °C, disproportionating into elemental iodine and iodine pentafluoride.
In chemistry, hydrogen halides (hydrohalic acids when in the aqueous phase) are diatomic, inorganic compounds that function as Arrhenius acids. The formula is HX where X is one of the halogens: fluorine, chlorine, bromine, iodine, astatine, or tennessine. [1] All known hydrogen halides are gases at standard temperature and pressure. [2]
Astatine is known to bind to boron, [62] carbon, and nitrogen. [63] Various boron cage compounds have been prepared with At–B bonds, these being more stable than At–C bonds. [64] Astatine can replace a hydrogen atom in benzene to form astatobenzene C 6 H 5 At; this may be oxidized to C 6 H 5 AtCl 2 by chlorine.
Potassium bromide (K Br) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US. Its action is due to the bromide ion (sodium bromide is equally effective). Potassium bromide is used as a veterinary drug, in antiepileptic medication for dogs.
A classical example of a word equation is the commutation equation =, in which is an unknown and is a constant word. It is well-known [ 4 ] that the solutions of the commutation equation are exactly those morphisms h {\displaystyle h} mapping x {\displaystyle x} to some power of w {\displaystyle w} .
This category is limited to chemical compounds which contain inorganic bromine in a -1 oxidation state. These may be metal salts containing bromide ion such as potassium bromide , or more covalent bromides of metals or nonmetals such as tantalum(V) bromide or phosphorus tribromide .
