Bromine is a chemical element with symbol Br and atomic number 35 It is the third-lightest halogen and it exists in the form of fuming red-brown liquid at room temperature The commercial source of bromine is brine pools Major producers of bromine are Israel the U S and China The mass of bromine in oceans is about 0 0033 times to that of chlorine

Bromine is certainly as effective as chlorine when it comes to killing bacteria in recreational water but there are nuances to the question of which is better Chlorine is cheaper to buy holds up better under the hot sun and the technology for its use in pools is more developed and generally better understood But especially for the indoor pools bromine offers distinct advantages based on

Chemical Analysis of Bromine Trifluoride

The chemical analysis of bromine trifluoride (BrF 3) (HF) and bromine(Br ) constituting the principal impurities in bromine trifluoride have at room temperature vapor pressures considerably higher than pure bromine trifluoride (that of HF being 760 mmHg at 20C that of Br 180 mmHg and that of BrFa only 5 6 mmHg) Therefore these impurities vaporized first when the vessel

Bromine is in group 17 period 4 its symbol is Br Bromine has an atomic number of 35 and atomic mass of around 79 904 It is a part of the Halogens group its Electron configuration is [Ar] 3d104s24p5 it is a liquid at room temperature its melting point is at -7 2 degrees Celsius its boiling pint is

The key difference between bromine and iodine is that bromine is in the liquid state at room temperature whereas iodine is in the solid state Bromine and iodine are elements in the halide group or the group 17 of the periodic table Therefore both these elements have

Free bromine (Br 2) is not used in drinking water treatment It reacts far to quickly with organic substances and no residue will remain Bromine gives drinking water a terrible medicine-like taste Bromine should only be used in emergency cases Is bromine used for the disinfection of cooling tower water? Bromine can be used for the disinfection of cooling tower water Hypobromous acid is

QVF Bromine Processes

2Br-+ Cl 2 = 2Cl-+ Br 2 and the bromine is stripped with steam in the same column The second step is the purification of the bromine from water and chlorine by rectification in a separation column These steps are carried out in columns interlinked as shown in the block scheme A The purification is eased by the fact that bromine has a low solubility in water (only 28g-Br 2 /1000g-H 2 O) so

Bromine from ancient Greek meaning "stench" is a chemical element with symbol Br and atomic number 35 It is a halogen Free bromine does not occur in nature but occurs as colorless soluble crystalline salts analogous to table salt The high solubility of bromide ions has caused its accumulation in the oceans where it is abundantly

Bromine-containing compounds enter the atmosphere as the result of both natural and anthropogenic activities The major source compounds are CH 3 Br (both natural and anthropogenic in origin) the halons (manufactured for use as fire suppressants) and dibromomethane CH 2 Br 2 (emitted from the oceans) Destruction of these compounds results in the formation of a suite of inorganic Br

(symbol Br) jump to other results a chemical element Bromine is a dark red poisonous liquid and has a very strong unpleasant smell It is mainly found in the form of salts in seawater Word Origin early 19th cent from French brome from Greek brōmos 'a stink' + -ine See bromine in the Oxford Advanced American Dictionary Check pronunciation bromine Nearby words bromance noun

Bromine has 2 stable isotopes Br-79 (50 69%) and Br-81 (49 31%) At least another 23 isotopes are known to exist Many of the bromine isotopes are fission products Several of the heavier bromine isotopes from fission are delayed neutron emitters All of the radioactive bromine isotopes are relatively short lived The longest half life is the neutron deficient Br-77 at 2 376 days The longest

The bromine adsorption stage is of great importance for the purity of the final product Adding the reaction mixture to water without pre-adsorption of the bromine leads to complete absorption of the bromine by the bromide solution Remember that we get a solution rich in bromine ions Br - (aq) and therefore Br - 3(aq)

Bromine is used in everyday products such as pesticides and water treatment solutions Bromine is a reddish-brown gas that has a pungent smell and can irritate the skin nose and eyes Bromine was discovered in 1826 by A J Balard Most pesticide agents contain bromine because it is toxic when inhaled Bromine compounds work as soil fumigants
