permanganometry

It is therefore in common use in qualitative analysis that involves redox reactions (permanganometry).

In the most cases permanganometry is performed in a very acidic solution in which the following reaction occurs:

In analytical chemistry, a standardized aqueous solution of KMnO is sometimes used as an oxidizing titrant for redox titrations (permanganometry).

For instance, in permanganometry a slight faint persisting pink color signals the endpoint of the titration because of the color of the excess oxidizing agent potassium permanganate.

Using permanganometry we can estimate the quantitative presence of Fe, Mn, Fe and Mn when they are both present in a mixture, CO, NO, HO etc.
