\nThe correct answer is It is an oxidizing agent.
\n<\/section>\n
\nPotassium permanganate (KMnO\u2084) is a strong oxidizing agent. Its oxidizing properties are utilized in water purification to kill bacteria and other microorganisms (germs), and to oxidize impurities like dissolved iron and manganese, causing them to precipitate and be easily removed.
\n<\/section>\n
\nWhile potassium permanganate does kill germs, this action is a result of its oxidizing property. It does not dissolve impurities; rather, it helps in their precipitation after oxidation. It is distinctly an oxidizing agent, not a reducing agent. Therefore, its role as an oxidizing agent is the fundamental reason for its use in purifying drinking water.
