Permanganate titrations - Oxidation reduction titrations
These are titrations where potassium permanganate is utilized as an oxidising agent in acidic medium. The medium is organized by the make use of dilute sulphuric acid. Potassium permanganate carries out as a self-indicator. The potential reaction, while potassium permanganate performs like an oxidising agent, is :
2KMnO4 + 3H2SO4 → K2SO4 + 2MnSO4 + 3H2O + 5 [O]
Or MnO-4 + 8H+ + 5e → Mn2+ + 4H2O
Before the end point, the solution stay colourless (when KMnO4 solution is taken in burette) although after the equivalence point only one extra drop of KMnO4 solution imparts pink colour, that is presence of pink colour shows the end point. Potassium permanganate is required for the estimation of ferrous salts, oxalates, oxalic acid, hydrogen peroxide, etc. The solution of potassium permanganate is all time first standardised before its use.
