Introduction of Manganese Dioxide
Acidity and alkalinity: Manganese dioxide is a non-amphoteric oxide (not a salt oxide). It is a very stable black powdery solid at room temperature and can be used as a depolarizer for dry batteries. The laboratory often uses its oxidizing property and concentrated HCl to produce chlorine gas: MnO2 1,4- 4 HCl = MnCl 2 dec Cl 2 dec 2H 2 O manganese dioxide is a strong oxidant in acid medium
Manganese dioxide is a [MnO2] octahedron with oxygen atoms on top of octahedral corners, manganese atoms in octahedrons, and [MnO2] octahedrons joined together to form single or double chains. These chains and other chains are co-topped to form The tunnel structure of the void, the octahedron or the hexagonal close-packed, or the square densely stacked.
Manganese dioxide is an amphoteric oxide, and there is a corresponding salt of a perovskite structure such as BaMnO3 or SrMnO3 (obtained by a chemical reaction in a molten alkali system), and manganese tetrachloride is also present.
In the case of a reducing agent, it exhibits oxidative properties. For example, manganese dioxide is placed in a hydrogen stream and heated to 1400 K to obtain manganese oxide; manganese dioxide is heated in an ammonia gas stream to obtain brown-black dimanganese trioxide; and manganese dioxide is reacted with concentrated hydrochloric acid to obtain 1 chlorine. Manganese, chlorine and water.
In the case of strong oxidants, it also appears to be reducing. For example, manganese dioxide, potassium carbonate and potassium nitrate or potassium chlorate are mixed and melted to obtain a dark green melt, and the melt is dissolved in water to obtain a compound of potassium pentoxide, potassium manganate. It is a strong oxidant in acid medium.
Strong oxidant, does not burn itself, but does not help with flammable materials.
