A permanganátok a manganát aniont tartalmazó vegyületek összefoglaló neve. Mivel benne a mangán oxidációs száma +7, a permanganátion erős oxidálószer. Az ion tetraéderes geometriájú. A permanganátok oldata ibolya színű, semleges vagy enyhén lúgos közegben stabil. A pontos kémiai reakció függ a jelenlévő szerves szennyezőktől és a használt oxidálószertől. A triklóretén például nátrium-permanganáttal szén-dioxiddá, mangán-dioxiddá, nátriumionná Sodium permanganate appears as a purplish colored crystalline solid. Noncombustible but accelerates the burning of combustible material.
