Manganese is a chemical element with the symbol Mn and atomic number 25. It is often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses.
1.Manganese phosphating is used for rust and corrosion prevention on steel.
2. Ionized manganese is used industrially as pigments of various colors, which depend on the oxidation state of the ions.
3. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode (electron acceptor) material in zinc-carbon and alkaline batteries.
2. Manganese can also functions in the oxygen-evolving complex of photosynthetic plants.
