Dihydrate salt (NaBr·2H 2 O) crystallize out of water solution below 50.7 °C. [8] NaBr is produced by treating sodium hydroxide with hydrogen bromide. Sodium bromide can be used as a source of the chemical element bromine. This can be accomplished by treating an aqueous solution of NaBr with chlorine gas: 2 NaBr + Cl 2 → Br 2 + 2 NaCl
Bromide from the diet, naturally present in the blood, is used by eosinophils, white blood cells of the granulocyte class, specialized for dealing with multi-cellular parasites. These cells react the bromide with peroxide to generate hypobromite by the action of eosinophil peroxidase , a haloperoxidase enzyme which preferentially uses bromide ...
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:
Brining is typically a process in which meat is soaked in a salt water solution similar to marination before cooking. [2] Meat is soaked anywhere from 30 minutes to several days. The brine may be seasoned with spices and herbs. The amount of time needed to brine depends on the size of the meat: more time is needed for a large turkey compared to ...
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
A oxidation reaction between hypobromous acid (HBrO) and hypochlorous acid (HClO) can be used to produce bromous acid (HBrO 2) and hydrochloric acid (HCl). [citation needed] HBrO + HClO → HBrO 2 + HCl. A redox reaction of hypobromous acid (HBrO) can form bromous acid (HBrO 2) as its product: [citation needed] HBrO + H 2 O − 2e − → HBrO ...
Potassium bromide and sodium bromide were used as anticonvulsants and sedatives in the late 19th and early 20th centuries, but were gradually superseded by chloral hydrate and then by the barbiturates. [29] In the early years of the First World War, bromine compounds such as xylyl bromide were used as poison gas. [30]
The product took its name from a component of the original formula, sodium bromide; each dose contained 3.2 mEq/teaspoon of it. Bromides are a class of tranquilizers that were withdrawn from the U.S. market in 1975 due to their toxicity. Their sedative effect probably accounted for Bromo-Seltzer's popularity as a hangover remedy.
