Manganese is a chemical element; it has the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. First isolated in the 1770s, mangane
Potassium permanganate
…Potassium permanganate is the potassium salt of the tetrahedral transition metal oxo complex permanganate, in which four O2− ligands are bound to a manganese(VII) center. Potassium permanganate is odorless and slightly sweet and astringent in taste. It is soluble in water, sulfuric acid, acetic anhydride, and…
