2002年10月23日 · Aqueous bromine atoms were produced by laser flash photolysis of 1,2-dibromoethane at 248 nm in solutions containing bromide ions. Forward and reverse rate constants of the title reaction were determined as functions of temperature.

溴 ㄒㄧㄡˋ （英語： Bromine），是一種 化學元素， 化學符號 為 Br， 原子序數 為35，是一種 鹵素。 溴分子在 標準溫度和壓力 下是有揮發性的紅棕色液體，活性介於 氯 與 碘 之間。 純溴也稱 溴素。 溴蒸氣具有 腐蝕性，並且 有毒。 2007年約製造了556,000公噸的溴。 [7] 溴與其化合物可用來作為 阻燃劑 （溴化阻燃劑）、 淨水劑 、 殺蟲劑 、 染料 等等。 曾是常用消毒藥劑的 紅藥水 中就含有溴和 汞。 在照相術中，溴和碘與銀的化合物擔任感光劑的角色。 溴元素化學性質十 …

1 I{-}(aq) + 1 Br 2 (aq) = 1 I 2 (s) + 1 Br{-}(aq) For each element, we check if the number of atoms is balanced on both sides of the equation. I is not balanced: 1 atom in reagents and 2 atoms in products.

Study with Quizlet and memorize flashcards containing terms like Given the reaction: 2I-(aq) + Br2(l) ----- > 2Br- (aq) + I2(s) As the reaction takes place 1) The Br2 is oxidized, and becomes the oxidizing agent 2) The Br2 is reduced, and becomes the oxidizing agent 3) The Br2is oxidized, and becomes the reducing agent 4) The Br2 is reduced ...

2017年9月24日 · Br2 (aq) + 2e- --> 2Br- (aq). Aqueous bromine simply means Br2 that has been dissolved in water. Br- is the form of bromine in which an electron has been gained (full outer shell).

1 Br 2 (l) + 2 KI(aq) = 2 KBr(aq) + 1 I 2 (s) I is balanced: 2 atoms in reagents and 2 atoms in products. All atoms are now balanced and the whole equation is fully balanced:

Compound states [like (s) (aq) or (g)] are not required. If you do not know what products are, enter reagents only and click 'Balance'. In many cases a complete equation will be suggested. Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds to compute the rest.

溴离子与溴酸根离子在酸性溶液中的反应用下式表示，5Br− (aq)+BrO−3 (aq)+6H3O+ (aq)→3Br2 (aq)+9H2O (l)为了测量反应速率，制备了储备溶液，如下表所示：储备溶液的浓度Br− 储备溶液1.37MBrO−3 储备溶液7.10×10−3MH3O+ 储备溶液0.537M将下列体积的溶液进行混合制备反应混合物，见下表，测量了溴酸根离子的初始消失速率。
