摘　　要：电动势测定是重要的电化学测量技术之一,也是物理化学实验教学中的重要内容,通过原电池电动势的测定可以获得氧化还原反应的许多热力学性质,如反应的热力学函数变化值和反应的平衡常数,电解质溶液的活度系数、平衡常数、酸碱度,配合物的络合常数等。本文系统介绍电动势法在物理化学实验中的应用。Measuring electromotance is not only an important measurement in electrochemistry but also an important content of physicalchemistry experiment teaching. This measuring technique can be used to measure lots of thermodynamic properties ,such as thermodynamic function ,equilibrium constant ,activity coefficient ,pH value ,complexation constant etc. ,they are obtained by measuring electromotance. In this paper ,the application of measuring electormotance is introduced systematically.
