2MnO4− + H2O + 3e− → 2MnO2 + 4OH−
Ikhtisar
In basic or neutral solution, permanganate is reduced to manganese dioxide (MnO₂) rather than Mn²⁺. The purple solution produces a brown precipitate of MnO₂. This half-reaction is important in organic chemistry where KMnO₄ selectively oxidizes alkenes to diols under mild basic conditions (Baeyer test).

Contoh Sehari-hari
The Baeyer test uses cold dilute KMnO₄ to detect C=C double bonds in organic molecules, turning purple to brown with a precipitate.
Pentingnya dalam Industri
Basic permanganate oxidation is used in organic synthesis for controlled oxidation of alkenes and in water treatment for taste and odor removal.
