The oxidation state of bromine in bromate ion
Webb9 jan. 2006 · The amount of bromide and bromate are chosen, such that they cancel each other precisely: 5Br (-) + BrO3 (-) + 6H (+) ---> 3Br2 + 3H2O This reaction is not instantaneously, it takes some time to react all of the reactants. The amount of acid added is in excess. Not all acid will be reacted. After the reaction, 66.7% of the acid remains. WebbThe oxidation state of an atom is a measure of the degree of oxidation of an atom. It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge. Isotopes

Webb25 mars 2024 · Bromine is oxidized from the 0 to the +5 oxidation state in this reaction. Bromine is also reduced in this reaction, from the 0 to the -1 oxidation state. If we assume that two Br- ions are produced for each molecule of Br2 reduced, the reduction half-reaction would be written as follows. Webb13 apr. 2024 · Bromate formation is a complex process that depends on the properties of water and the ozone used. Due to fluctuations in quality, surface waters require major …
Webb26 aug. 2014 · The present study aims to minimize BrO 3− formation and eliminate BrO 3− generated during the ozonation of drinking water, particularly in packaged drinking water. Results show that the Br − and BrO 3− levels in GAC-treated water decreased in both bench- and pilot-scale experiments. Webb12 maj 2024 · Bromination of organic substances is still an important reaction in modern synthetic chemistry. In view of the increasing demand for sustainable synthetic …
WebbOf them, bromate has attracted the most intensive attention. It was previously regarded as a byproduct that typically occurred in ozone-based oxidation processes. However, for the past decade, bromate formation has been detected in other oxidation processes such as CuO-catalyzed chlorination, SO 4--based oxidation, and ferrate oxidation processes.
