Bromine water, Br 2. Bromine water is an oxidizing, intense brown mixture containing diatomic bromine (Br 2) dissolved in water (H 2 O). [1] It is often used as a reactive in chemical assays of recognition for substances which react with bromine in an aqueous environment with the halogenation mechanism, mainly unsaturated carbon compounds (carbon compounds with 1 or more double or triple bond(s)).
CLEAPSS provides: [5] termly newsletters for primary and secondary schools, a wide range of free publications, model risk assessments, special risk assessments, low-cost training courses for technicians, teachers and local authority officers, a telephone helpline which takes nearly 7,000 calls per year, a monitoring service, e.g. for mercury ...
The hypobromite ion, also called alkaline bromine water, is BrO −. Bromine is in the +1 oxidation state. The Br–O bond length is 1.82 Å. [1] Hypobromite is the bromine compound analogous to hypochlorites found in common bleaches, and in immune cells. In many ways, hypobromite functions in the same manner as hypochlorite, and is also used ...
Chemical Safety Reports are the main end point for data assessment under REACH (the European Community Regulation on chemicals and their safe use, concerning the Registration, Evaluation, Authorisation and Restriction of Chemical substances [4]) in which hazard and exposure data are considered together to assess the risk of a substance. [5]
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
The use of assessment factors allows for laboratory, single-species and short term toxicity data to be extrapolated to conservatively predict ecosystem effects and accounts for the uncertainty in the extrapolation. The value of the assessment factor is dependent on the uncertainty of the available data and ranges from 1-1000. [1] [6] [7]
Chemical safety includes all safety policies, procedures and practices designed to minimize the risk of exposure to potentially hazardous chemicals.This includes the risks of exposure to persons handling the chemicals, to the surrounding environment, and to the communities and ecosystems within that environment.

Addition of bromine to water gives hypobromous acid and hydrobromic acid (HBr(aq)) via a disproportionation reaction. Br 2 + H 2 O ↽ − ⇀ {\displaystyle {\ce {<=>>}}} HOBr + HBr In nature, hypobromous acid is produced by bromoperoxidases , which are enzymes that catalyze the oxidation of bromide with hydrogen peroxide: [ 2 ] [ 3 ]
