Abstract:
The stoichiometry between permanganate and cyanide ions in aqueous solution has been investigated. The reaction leading to the formation of a dark brown precipitate is represented by the equation. 2MnO¯4 + 3CN¯ + 2H02 = 2Mn02 + 30CN¯ + 20H lnteractin of excess of ice-cooled 3M aqueous potassium cyanide and 0.1 M aqueous potassium permanganate, initially produces an unstable manganese (IV) cyano species which is finally reduced to manganese (III) giving hepatopotassium - u Oxo-bis6pentacyano-manganate (III) cyanide. The oxo bridged [Mn2O(CN10)]-6 ion appears to exist in solution.
