Abstract:

This paper mainly introduces the laboratory teaching experiment, preparation of trans/cis-[Co(en)2Cl2]Cl and determination of kinetic constants of their hydrolysis reaction, which has been carried out for 10 years and particularly designed for top-talented chemistry-majored students in Xiamen University. This experiment covers the basic theoretical knowledge such as the cis/trans isomers, the crystal field splitting energy and the hydrolytic reaction kinetics of the complex, and the experimental operation skills such as the preparation of cis/trans isomers, the spectral identification and the hydrolytic reaction kinetics research in different media. The purpose of this experiment was to let the students have a thorough understanding of the preparation of cis/trans isomers, the isolation and identification methods, and the methods of kinetic study on complex hydrolysis reaction. It is helpful for students to understand intuitively and profoundly that the structure determines property, to strengthen the deep integration of theory and experiment, as well as to cultivate the abilities of analysis, judging and critical thinking.
