Permanganate ion MnO

Uncombined elements are all given zero oxidation state. Consider (a) manganese in the permanganate ion, MnO there are four... 

In the laboratory you have observed the reaction of ferrous ion, Fe+i(aq), with permanganate ion, MnOiYaqJ, and also the reaction of oxalate ion, CiOi2(aq), with permanganate ion, MnO (aq). These studies show that the rate of a reaction depends upon the nature of the reacting substances. In Experiment 14, the reaction between IO and HSO3" shows that the rate of a reaction depends upon concentrations of reactants and on the temperature. Let us examine these factors one at a time. 

The permanganate ion, MnO, meets the criteria set forth in the preceding paragraph Manganese is in a formal oxidation state of + 7 and combined with four oxide ions. The molecular orbital diagram for tetrahedral complexes in Fig. 11.52 allows us to identify possible LMCT transitions. In any tetrahedral complex, the four... 

This activity is shown, for example, by the decolorizing of an acidic solution of potassium permanganate by addition of hydrogen peroxide. The permanganate ion, MnO , is reduced to the manganous ion, Mn++, and free oxygen is liberated. The electron reactions are... 

Permanganate ion, MnO, is reduced to Mn in distinctly acid solution, as is Mn02. The reduction product of permanganate in neutral or alkaline solution may be MnO(OH), Mn02, or Mn04. ... 

The permanganate ion, MnO, , has a deep violet color. Do you think the color of this compound is due to an LF, LMCT, MLCT, or MMCT transition Explain your reasoning. 

The manganate ion can be oxidized to permanganate ion, MnO , which contains Mn+ The electron reaction for this process is... 

Example 8 Will the permanganate ion, MnO,-. liberate O from water in the presence of acid (H")7... 

Permanganate ion (MnO/" ) has a detection limit of 1(T M, and molecular oxygen is not required [17]. Chlorates, chlorites and bromates were found not to interfere, even when present in high concentrations [8].
