When concentrated sulfuric acid is added to potassium permanganate, an explosive compound is produced. Which product is formed in this reaction?

1. Mn2O7
2. MnO2
3. MnSO4
4. M2O3

Correct answer: Mn2O7

Solution

The reaction between concentrated sulfuric acid and potassium permanganate produces manganese heptoxide (Mn2O7), which is known for its explosive properties. This compound forms due to the oxidation of manganese in the permanganate ion under acidic conditions.
