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.
As energy is drawn from the system, the sodium disulfide becomes sodium polysulfide, and the sodium tribromide becomes sodium bromide. This reaction can be reversed when a current is supplied to the electrodes, and the system's chemical salts are recharged. The system is sometimes defined as a fuel cell because the electrodes are not consumed ...
The classic case is sodium bromide, which fully dissociates in water: NaBr → Na + + Br −. Hydrogen bromide, which is a diatomic molecule, takes on salt-like properties upon contact with water to give an ionic solution called hydrobromic acid. The process is often described simplistically as involving formation of the hydronium salt of bromide:
It originally contained sodium bromide and acetanilide, both toxic substances which were eventually removed. Its current formulation contains the pain reliever aspirin and two reactive chemicals – sodium bicarbonate and citric acid – which creates effervescence when mixed with water. Sodium bicarbonate is an antacid.
In September 2012, Albemarle was one of the three chemical companies that backed the Citizens for Fire Safety industry group that lobbied for use of flame retardant in consumer products including furniture and baby products. [27] In 2014, Albemarle completed the sale of its antioxidant, ibuprofen and propofol businesses to SI Group. [28]
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 ...
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 ]
Bromates are formed many different ways in municipal drinking water. The most common is the reaction of ozone and bromide: Br − + O 3 → BrO − 3. Electrochemical processes, such as electrolysis of brine without a membrane operating to form hypochlorite, will also produce bromate when bromide ion is present in the brine solution.
