Abstract:

This paper mainly introduces the laboratory teaching implementation results and discussions of "determination of kinetic constants of the hydrolysis reaction of trans/cis-[Co(en)2Cl2]Cl complexes", which has been carried out for 10 years and particularly designed for top-talented chemistry-majored students at Xiamen University. Students were guided to discuss and explore the effects of reaction medium and temperature on the hydrolysis reaction of trans/cis-[Co(en)2Cl2]Cl, based on the dynamic experimental data and results. In light of this, students could directly understand the differences in the hydrolysis reaction kinetics behavior of trans/cis isomer with different structure, and the meaning of "structure decides the nature". Their ability of induction, summary, analysis, judgment and critical thinking can be cultivated.

Key words: trans/cis-[Co(en)2Cl2]Cl, Kinetics of hydrolysis reaction, Analysis and discussion of experimental results
