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
