Permanganate ion (MnO4-) is used in water purification to remove oxidizable substances. Complete and balance the following reaction for the removel of sulfide, cyanide, and sulfite. Assume that theresult of the reaction is a basic solution. Place charges and state elements are in.
(a) MnO4-(aq) + S2-(aq) yields MnS(s) + S(s)
(b) MnO4-(aq) + CN-(aq) yields CNO-(aq) + MnO2(s)
(c) MnO4-(aq) + SO32-(aq) yields MnO2(s) + SO42-(aq)
