【标准电极电势表】
标准电极电势可以用来计算化学电池或原电池的电化学势或电极电势。
标准电极电位是以标准氢原子作为参比电极，即氢的标准电极电位值定为0，与氢标准电极比较，电位较高者为正，电位较低者为负。
表中电极电势以以下条件测得（(s)：固体；(l)：液体；(g)：气体；(aq)：水溶液；(Hg)：汞齐）：
* 参比电极：标准氢电极，所有离子的数据都在水溶液测得
* 活性度：统一为纯固体、纯液体或水溶液
* 温度：298.15K／25摄氏度
* 水溶液或汞齐之有效离子浓度：每公升1摩
* 气体反应物分压：1大气压／101325帕
单击每栏上方的符号可将数据按元素符号、反应物、产物或标准电极电势值排序。
