电源电动势的理化解释和应用

Explanation and Application of Power Potential

电源的电动势是物理学当中的一个重要概念,一般的教材中只做简单描述,本文着重介绍电动势的来源、电极电势大小和溶液浓度的关系以及电动势在计算热力学函数、平衡常数、PH测定值以及溶液滴定过程中的一些应用。

As an important concept in physics, power potential is but simply described in normal courses. Fotential source, potential value and the relationship among them and solution concentration are consequently introduced, based on which the calculation of thermodynamic function, equilibrium constant, pH value and the process of titration are discussed in details.
