溴酸的酸性和溴化氢的酸性谁的强

x = 3
3BrFx + 5H2O = HBrO3 + 9HF + Br2 + O2
配平：有5个O,那么HBrO3和O2系数都是1,H有10g,那么HF系数为9.
由于BrF3既是氧化剂又是还原剂,H2O是还原剂,不好比较.

氯的非金属性比溴强,元素的非金属性越强,最高氧化物的水合物酸性越强.
氯比溴少一层电子,原子半径比溴小.
但主要在非金属性上.

楼上的我无语
卤素在负一价态貌似没有氧化性,他们不能降价了.
HBRO3>HCLO3>HIO3
这是在主族非金属元素里面可以看到的次级周期性现象,可以解释为d轨道的全满使溴的核外电子对核的屏蔽减少,即电正性增强,氧化性也增强；另外氯的半径比较小,使得其与氧原子间可以形成较强的d-p配键,又减弱了其氧化性.至于氯酸的比碘酸的强是元素电负性递减的正常现象,因此只有溴酸例外了.
同样的情况出现在氧族元素中,硒酸氧化性强于硫酸.(引用别人的,

题目的意思：用氯气去氧化氢溴酸的反应（氢溴酸是碘化氢HBr,通常卤族的氢化物在水溶液中称为某酸,如氯化氢溶于水叫盐酸,氟化氢在水中称为氢氟酸）
所以化学反应方程式
Cl2+ 2HBr= 2HCl + Br2

3 BrFx+5 H2O=HBr+9 HF+Br2+2.5 O2 ,所以X应该是3

是溴酸根离子和亚硝酸根离子

不是的
就是生成次溴酸和氢溴酸
Hypobromous acid
Space-filling model of hypobromous acidHypobromous acid is a weak,unstable acid with chemical formula HOBr.It is also called bromic(I) acid,bromanol or hydroxidobromine.It occurs only in solution and has chemical and physical properties that are very similar to those of hypochlorous acid.
In aqueous solution,hypobromous acid partially dissociates into the hypobromite anion OBr− and the cation H+.The salts of hypobromous acid are also called hypobromites.Like the acid,these salts are unstable and when evaporated or boiled to dryness,they undergo a disproportionation reaction,yielding the respective bromate and bromide salts.
When pure bromine is added to water,it forms hypobromous acid and hydrobromic acid (HBr):
Br2(l) + H2O(l) → HOBr(aq) + HBr (aq)
HOBr is used as a bleach,an oxidizer,a deodorant,and a disinfectant,due to its ability to kill the cells of many pathogens.The compound is generated in warm-blooded vertebrate organisms especially by eosinophils,which produce it by the action of eosinophil peroxidase,an enzyme which preferentially uses bromide.[1] Bromide is also used in hot tubs and spas as a germicidal agent,using the action of an oxidizing agent to generate hypobromite in a similar fashion to the peroxidase in eosinophils.It is especially effective when used in combination with its congener,hypochlorous acid.

溴酸可以直接把碘离子氧化成碘酸根离子,而次氯酸不行,所以溴酸氧化性比次氯酸强.
希望对你有所帮助!

（1）+5．（2）Al ³⁺ ，（3维生素，（4）乳化作用，（5）①③⑤，（6）I、①④，II、②④．

反应式如下：
3BrF₃ + 5H₂O ＝ 9HF + HBrO₃ + Br₂ + O₂
被氧化的水占2/5
被还原的BrF₃占2/3
∴两者的物质的量之比为1：1
BrF₃ H₂O

（41.1g） 5.4g

不存在偏铝酸,这是事实
溴酸>亚硫酸略大于磷酸>碳酸略大于氢硫酸>硅酸>铝酸

3BrFx + 5H2O ----> HBrO3 + 9HF + Br2 + O2
