平衡电极电位,也称可逆电极的电位。在一个可逆电极中,金属成为阳离子进入溶液以及溶液中的金属离子沉积到金属表面的速度相等时,反应达到动态平衡,亦即正逆过程的物质迁移和电荷运送速度都相同,此时该电极上的电位值称为平衡电极电位。
阴极极化:直流电通过电极时,阴极电位偏离平衡电位向负的方向移动的现象。
The cathode polarization: dc through electrode, the cathode potential deviating from the balance to the negative potential moves in the direction of the phenomenon.
硫化矿物电极电位不是可逆电极的平衡电位,而是不可逆电极的稳定电位。
The electrode potential of sulfide minerals is not an equilibrium potential of a reversible electrode, but a steady potential of a nonreversible electrode.
用其为指示电极,以非平衡方式进行快速电位滴定。
By using this electrode as the indicator electrode, tetradecylpyridinium chloride can be titrated with dodecyl sulfonate potentiometrically in a fast, continuous, non-equilibrium way.
