摘要
利用平衡移动原理可以定性判断浓度对电极电势的影响.在改变除电对以外离子的浓度、改变电对其中1种离子的浓度、同时改变电对本身2种离子的浓度的3种情况下,能斯特方程和该法均可得到相同的结论,但后者更简单.
The effect of concentration on electrode potential could be made qualitative statements according to the chemical equilibrium principle.When the concentration of a substance(one of the redox pair,both of them,or the related ion) have changed,the Nernst equation and chemical equilibrium principle can get the same conclusion,but the latter is more simpler.
