温度对电极电位精确度影响及其校正

The temperature effect on precision of electrode potential and its correction

以氯化钠溶液电解中的氯电极为例 ,论述了氯电极的标准电位 φ 怎样随温度变化 ,参比电极和标准氢电极电位又是怎样变化 ,从而引出“等温温度系数”和“温差温度系数”两个基本概念 。

Taking the Cl 2 electrode in NaCl electrolysis as example,we discuss how the standard potential of Cl 2 electrode is changing with temperature,and how is the change of the reference electrode and standard potential of Cl 2 electrode,and then introduce two basic concepts,the isothermal coefficeient and diffirential temperature coefficient,and develop their formulae.
