摘要：

电解液是电化学体系的重要组成部分。近年来，科研领域新出现的电解液概念极大地丰富了电解液的内涵。为拓宽学生的知识构架，培养学生的创新和科学发展意识，有必要将新型的电解液概念引入物理化学课堂教学和实验教学中。本实验利用深共熔溶剂同时具备溶剂和电解液特点，对基于氯化胆碱的两种深共熔溶剂的粘度和电导率进行测定，并进一步应用于玻碳电极和Pt电极上CuCl₂的循环伏安测定。本实验将科研成果引入教学中，引导学生了解学科领域的发展，有助于学生科学思维能力的培养，激发学生对科学研究的兴趣。

关键词: 深共熔溶剂, 电解液, 电导率, 粘度, 循环伏安技术

Abstract:

Electrolytes are critical in electrochemistry. Recently, novel concepts of electrolytes have emerged, which give new insights into traditional electrolytes. To broaden students' knowledge and cultivate innovative and scientific development thinking, it is necessary to introduce these new concepts into physical chemistry teaching. In this experiment, two types of deep eutectic solvents based on choline chloride were prepared as solvent and electrolyte, and then the viscosity and conductivity were measured to improve the understanding of the characteristics of deep eutectic solvents. Lastly, cyclic voltammetric experiments of CuCl₂ with a glassy carbon electrode and Pt electrode in deep eutectic solvents were carried out. Here, we introduce scientific research into physical chemistry teaching, to cultivate students' scientific thinking abilities and improve their interests in chemistry research.

Key words: Deep eutectic solvents, Electrolyte, Conductivity, Viscosity, Cyclic voltammetry
