What is the cation and anion in MnO2?
What is the cation and anion in MnO2?
The oxidation number of the oxide anion is -2 . Since there are 2 oxide ions, the total oxidation number for the oxide is -4 . Since the sum of the oxidation numbers must be 0 , the oxidation number of the manganese cation is +4 . Therefore, MnO2 is the ionic compound manganese(IV) oxide.

What are the ions in MnO2?
This compound, called manganese dioxide, also contains two oxygen ions, each with an oxidation number of -2. The manganese ion also exhibits other oxidation numbers, such as +2 and +7.
Is MnO2 positive or negative?
From these XRD pattern comparisons, it is clear that only MnO2 on the negative elec- trode had an obvious redox reaction in the electrochemical charging/discharging process of the symmetric supercapacitors, and MnO2 on the positive electrode served as a reference elec- trode with high valence Mn ions (4+).
