标准电极电势表.doc

_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。本表中所给出的电极电势以标准氢电极为参比电极，溶液中离子有效浓度为1mol/L，气体分压为100kPa，温度为298K，所有离子的数据都在水溶液中测得。123456789单击每栏上方的符号可将数据按元素符号或标准电极电势值排序。注：(s) 固体；(l) 液体；(g) 气体；(aq) 水溶液；(Hg) 汞齐。半反应E(V)注 1来源Ba+eBa(s)4.381013Sr+eSr(s)4.101113Ca+eCa(s)3.81113Pr3+ePr2+3.111N2(g) + H+eHN3(aq)3.096Li+eLi(s)3.04015N2(g) + 4H2O + 2e2NH2OH(aq) + 2OH3.046Cs+eCs(s)3.0265Ca(OH)2(s) + 2eCa(s) + 2
