Salt lakes and brine wells may have higher bromine concentrations: for example, the Dead Sea contains 0.4% bromide ions. [54] It is from these sources that bromine extraction is mostly economically feasible. [55] [56] [57] Bromine is the tenth most abundant element in seawater. [58] The main sources of bromine production are Israel and Jordan. [59]
A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]
An old qualitative test for the presence of the alkene functional group is that alkenes turn brown aqueous bromine solutions colourless, forming a bromohydrin with some of the dibromoalkane also produced. The reaction passes through a short-lived strongly electrophilic bromonium intermediate. This is an example of a halogen addition reaction. [18]
Anthropogenic and natural sources of bromine. The major sources include sea spray, salt lakes, marshes, volcanos, anthropogenic sources. Sinks include exchange of brominated compounds with the stratospheric and troposphere.Bromine's chemistry is linked to other halogens such as chlorine and iodine amplify atmospheric cycling that contributes to troposphere and stratosphere ozone layer ...
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 .
