不同的价态之间,电势是不同的.需要根据具体情况判断的.
一般ClO3-被还原到Cl-；
Cl-的价态升高就是被氧化.
其他类似问题
问题1：标准电极电势表问题标准电极电势表格中镉II有两个 一个是Cd2+ + 2e- ===Cd -0.4026V还有一个是Cd2+ + 2e- === Cd（Hg） -0.352V那个Hg代表什么 好的一定采纳
Hg代表Cd溶于汞,就是Cd汞齐,Hg代表汞
问题2：标准电极电势的问题MnO4(-)在酸性环境下的标准电极电势是1.507v.但是酸性环境的pH是多少啊?[化学科目]
pH = 0
标准电极电势,
所有离子的物质的量浓度 c = 1 mol/L,
所有气体的分压 p = pΘ = 10^5 Pa（也有的书写pΘ = 101325 Pa）.
问题3：怎么计算标准电极电势利用H*/H2的标准电极电势和HAC的电离常数计算2HAC+2e=H2+2AC-的标准电极电势啊
首先,要明白标准电极电势的定义
各物质都是 1mol每升（严格说,是标态） 时的电极电势
2HAC+2e=H2+2AC-
即HAC,AC-,H2都是1mol每升
由于已知 HAC H2
它的标准电极电势 是0v
现在求出了氢离子浓度,所以用
能斯特方程对他进行修正即可,记住H2也是1mol每升
带入求出
还有什么问题不懂得,你说就行了
问题4：标准电极电势是电极电势大的做正极吗[数学科目]
是电极电势大的为正极,但与标准电极电势无关.
问题5：求全元素的电负性与标准电极电势表[化学科目]
氢 2.1 锂 0.98 铍 1.57 硼 2.04 碳 2.55 氮 3.04 氧 3.44 氟 3.98
钠 0.93 镁 1.31 铝 1.61 硅 1.90 磷 2.19 硫 2.58 氯 3.16
钾 0.82 钙 1.00 锰 1.55 铁 1.83 镍 1.91 铜 1.9 锌 1.65 镓 1.81 锗 2.01 砷 2.18 硒 2.48 溴 2.96
铷 0.82 锶 0.95 银 1.93 碘 2.66 钡 0.89 金 2.54 铅 2.33
一般来说,电负性大于1.8的是非金属元素,而小于等于1.8的往往是金属元素（当然,其中也存在例外）
