Bromide is present in typical seawater (35 PSU) with a concentration of around 65 mg/L, which is about 0.2% of all dissolved salts. Seafood and deep sea plants generally have higher levels than land-derived foods. Bromargyrite—natural, crystalline silver bromide—is the most common bromide mineral known but is still very rare. In addition to ...
Bromide in source waters can be converted by ozone into bromate, a potent carcinogen that is regulated in the United States, as well as other brominated DBPs. [ 1 ] As regulations are tightened on established DBPs such as THMs and HAAs, drinking water treatment plants may switch to alternative disinfection methods.
Potassium bromate may be used in the production of malt barley, but under safety conditions prescribed by the U.S. Food and Drug Administration (FDA), including labeling standards for the finished product. [5] It is a powerful oxidizer (electrode potential = 1.5 volts, similar to potassium permanganate). [citation needed]
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. See also [ edit ]
The bromide anion is not very toxic: a normal daily intake is 2 to 8 milligrams. [75] However, high levels of bromide chronically impair the membrane of neurons, which progressively impairs neuronal transmission, leading to toxicity, known as bromism. Bromide has an elimination half-life of 9 to 12 days, which can lead to excessive accumulation ...
The high-bromine brines in the Appalachian Basin are found in Silurian and Devonian rocks, in Pennsylvania, Ohio, and West Virginia. The principal source of the brine in Ohio and West Virginia was the Pottsville Formation, also called the Big Salt Sand. In Pennsylvania, bromine brine was pumped from the Pocono Sandstone. [2]
Sodium bromide is an inorganic compound with the formula Na Br. It is a high-melting white, crystalline solid that resembles sodium chloride . It is a widely used source of the bromide ion and has many applications.
Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...
