Because manganese is in the + 7 oxidation state, the permanganate (VII) ion is a strong oxidizing agent . The ion has tetrahedral geometry . Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media . The exact chemical reaction is dependent upon the organic contaminants present and the oxidant utilized . For example, trichloroethene (C H Cl) is oxidized by sodium permanganate to form carbon dioxide (CO), manganese dioxide (MnO), sodium ions (Na), hydronium ions (H), and chloride ions (Cl). </P> <P> In an acidic solution, permanganate (VII) is reduced to the colourless + 2 oxidation state of the manganese (II) (Mn) ion . </P>
