Abstract:

Elemental chemistry is an important part of inorganic chemistry. The study on the properties and reaction rules of inorganic compounds through experimental methods can make the traditional descriptive teaching a three-dimensional teaching that is easy to be received by students. This experiment includes the synthesis of simple inorganic compounds and the utilization of temperature-programmed reduction technique (TPR) to investigate the redox properties of those inorganic compounds. The TPR technique can directly reflect the reduction process of the samples and provide the qualitative information of the reduction ability from the peak location, quantitative information of the reduced species from the peak intensity, and the interaction between the components. The TPR technique can be easily applied in college teaching for chemical laboratory courses.

Key words: Inorganic compounds, Redox properties, Temperature-programmed reduction
