- explain kinetic and thermodynamic stability of coordination entities
О курсе
We have created this course to help you understand the foundational information about
coordination compounds, which are of very much interest in our everyday life. Naturally
occurring coordination compounds hemoglobin and myoglobin are vital to living organisms. Many enzymes, that regulate biological processes, are coordination compounds. Chlorophyll is of very great importance for the plant world. Many technologically important processes are based on coordination compounds as catalysts. Coordination compounds of many metal ions are used for their selective precipitation, for their extraction from aqueous solutions, for their detection and determination.
Для кого этот курс
The course is designed for undergraduate chemistry students, but it may be useful for all chemistry students interested in new knowledge in this eld.
Начальные требования
Basic knowledge of general, inorganic and organic chemistry are required before taking this course.
