Pick out the incorrect statement
1
MnO42– is quite strongly oxidizing and stable only in very strong alkalies. In dilute alkali, water or acidic solutions, it dispropotionates
2
In acidic solutions, MnO4 is reduced to Mn2+ and thus, KMnO4 is widely used as oxidizing agent
3
KMnO4 does not act as oxidizing agent in alkaline medium
4
KMnO4 is manufactured by the fusion of pyrolusite ore with KOH in presence of air or KNO3, followed by electrolytic oxidation in alkaline solution
