उत्तर
Potassium permanganate is a strong oxidising agent in acidic environments. In the presence of dilute sulphuric acid, it interacts as shown below.
\[\ce{2KMnO4 + 3H2SO4 -> K2SO4 + 2MnSO4 + 3H2O + 5O}\]
The reaction actually involves the reduction of \[\ce{MnO^-_4}\] ions to Mn2+ ions.
\[\ce{MnO^-_4 + 8H+ + 5e- -> Mn^{2+} + 4H2O}\]
