Question
Explain the action of Conc.$H_2SO_4$ on potassium permanganate.
✓
Answer
1. On treating with cold conc.$H_2SO_4$, it decomposes to form manganese heptoxide, which subsequently decomposes explosively.
2. With hot Conc.$H_2SO_4$, potassium permanganate give $MnSO_4$ [Manganese(II) sulphate]
2. With hot Conc.$H_2SO_4$, potassium permanganate give $MnSO_4$ [Manganese(II) sulphate]
