Oxidation of Chloride Ion by Permanganate
Description: Purple permanganate ion is reduced and almost decolorized (to Mn(II) ) by chloride ion in acid solution. Purple permanganate ion is reduced to green manganate ion by chloride ion in basic solution. In neutral chloride solution, there is no reaction.
