浓差电池电动势测定方法的改进研究

The Improvement on the Method of Measurement of Concentration Cell Electromotive Force

浓差电池电动势的测定是原电池电动势测定实验的一部分,现行实验教材中的测定方法是不同浓度的电解质溶液通过盐桥连接。本文从改进传统的盐桥方法出发,采用双联电池的方法来对浓差电池电动势的测定进行了探索,发现改进后的实验结果基本上可以和传统盐桥方法接近。

Measurement of concentration cell electromotive force was part of the experiment of of measurement of gal- vanic battery electromotive force, the method was different concentrations of electrolyte solution connected by a salt bridge in the present experimental teaching material. There was some improvement on the traditional method of salt bridge. A double - battery approach was carried out to explore the determination of concentration cell electromotive force. We found that our results were very close to the traditional method.
