Manganese is an important chemical element, and its compounds have many applications in life. In manganese compounds, divalent manganese and total manganese are two common forms, which are widely used in chemical and metallurgical industries. So, what is the difference between divalent manganese and total manganese? Next, we will uncover the mystery of this chemical element for you. Introduction to

1.
divalent manganese, namely Mn2, is a kind of valence of manganese element, it widely exists in manganese ore. Total manganese refers to the sum of all oxidation states of manganese in the sample. In many chemical experiments and industrial production, we need to distinguish between divalent manganese and total manganese.

2. properties
Divalent manganese is a manganese element in a lower oxidation state, usually in a valence state of 2. It is usually a colorless or pink compound that is used in chemical production to make products such as dyes and catalysts. The total manganese refers to the total amount of manganese in various oxidation states in the sample, including 2, 3, 4, 6 and other valence states.

3. uses
divalent manganese in industrial production has a wide range of uses, such as for the preparation of potassium manganate, manganese salt and other products. The content of total manganese is of great significance in environmental monitoring and water quality testing, and can be used to assess the degree of water pollution.

4. detection method
In order to accurately detect the content of divalent manganese and total manganese in the sample, we usually use different chemical analysis methods. For the detection of divalent manganese, the commonly used methods include titration, UV-Vis spectrophotometry, etc. The detection of total manganese requires the reduction of various oxidation states of manganese in the sample, and then the determination.

5. Conclusion
In general, divalent manganese and total manganese are two different states of manganese, and they have different applications in the fields of chemical industry and environmental monitoring. By accurately detecting and distinguishing the content of divalent manganese and total manganese, we can better grasp the chemical properties of the sample, and provide strong support for research and production in related fields. It is hoped that through the introduction of this article, you will have a deeper understanding of divalent manganese and total manganese.
