The bromate anion, BrO − 3, is a bromine-based oxoanion.A bromate is a chemical compound that contains this ion. Examples of bromates include sodium bromate, (NaBrO 3), and potassium bromate, (KBrO 3).. 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
NO TE : This method is for the analysis of simple bromide ion rather than total bromide, as analysis using the ion-selective electrode is not preceded by a distillation step. 1.2 The method detection limit is 0.2 mg/L. Bromide concentrations from 0.1 to 1,000 mg/L may be measure d.
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine.Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826 ...
The molecular ion peaks (M+ and M+2) each contain one chlorine atom - but the chlorine can be either of the two chlorine isotopes, 35 Cl and 37 Cl. The molecular ion containing the 35 Cl isotope has a relative formula mass of 78. The one containing 37 Cl has a relative formula mass of 80 - hence the two lines at m/z = 78 and m/z = 80.. Notice that the peak heights are in the ratio of 3 : 1.

Create. 2004-09-16. Cetyltrimethylammonium bromide is the organic bromide salt that is the bromide salt of cetyltrimethylammonium; one of the components of the topical antiseptic cetrimide. It has a role as a surfactant and a detergent. It is a quaternary ammonium salt and an organic bromide salt. It contains a cetyltrimethylammonium ion.
bromide. An chemical compound containing a bromine ion Br-; once used as a hypnotic and sedative and for headaches—e.g., Bromo-Seltzer. It was withdrawn from human use in 1975 due to chronic toxicity. It is of current interest as an industrial toxin—e.g., methyl bromide, which is used as a solvent, degreaser and fumigant.
Halides ions are fluorides chloride, bromide, and iodide. Many halide compounds of alkali and alkali earth metals are soluble in water. These halide ion compounds exist in different forms in nature as solutions, precipitates and solids. Some halide compounds have colours which is useful to identify them. Halide compounds of Pb and Ag have colours.
Because the chloride ion is a weaker nucleophile than bromide or iodide ions, hydrogen chloride does not react with primary or secondary alcohols unless zinc chloride or a similar Lewis acid is added to the reaction mixture as well. Zinc chloride, a good Lewis acid, forms a complex with the alcohol through association with an unshared pair of ...
When drinking water containing bromide is exposed to ozone, bromate ion, a powerful oxidizing agent, is formed. Two significant recalls of drinking water involving bromate have occurred: Wegmann ' s Food You Feel Good About Spring Water Recall in 2006, and Coca-Cola's Dasani in 2004. (25)
