Potassium permanganate, KMnO4, is a powerful oxidizing agent. The products of a given redox reaction with the permanganate ion depend on the reaction conditions used. In basic solution, the following equation represents the reaction of this ion with a solution containing sodium cyanide:
MnO4-(aq)+ CN-(aq)} = MnO2(s)+ CNO-(aq)
Since this reaction takes place in basic solution, H_2O(l) and OH^-(aq) will be shown in the reaction. Places for these species are indicated by the blanks in the following restatement of the equation:
MnO4-(aq)+ CN^-(aq)+______ = MnO2(s)+ CNO-(aq)+________
What are the coefficients of the reactants and products in the balanced equation above? Remember to include H2O(l) and OH^-(aq) in the blanks where appropriate.
