An explosion takes place when conc. `H_(2)SO_(4)` is added to `KMnO_(4)` due to formation of

Options

A. `Mn_(2)O_(7)`
B. `MnO_(2)`
C. `MnSO_(4)`
D. `(MnO_(3))_(2)SO_(4)`

Explanation

To solve the question regarding the explosion that occurs when concentrated \( H_2SO_4 \) is added to \( KMnO_4 \), we will analyze the reaction step by step.

### Step 1: Identify the Reactants
The reactants in this reaction are concentrated sulfuric acid (\( H_2SO_4 \)) and potassium permanganate (\( KMnO_4 \)).

### Step 2: Understand the Reaction
When concentrated \( H_2SO_4 \) is added to \( KMnO_4 \), it acts as a strong oxidizing agent. The concentrated sulfuric acid can dehydrate the permanganate ion and facilitate the formation of manganese oxides.

### Step 3: Write the Reaction
The main products formed when \( KMnO_4 \) reacts with \( H_2SO_4 \) include potassium sulfate (\( K_2SO_4 \)), manganese(VII) oxide (\( Mn_2O_7 \)), and water. The simplified reaction can be represented as:

\[ 2 KMnO_4 + 3 H_2SO_4 \rightarrow K_2SO_4 + Mn_2O_7 + 3 H_2O \]

### Step 4: Identify the Explosive Product
The formation of manganese(VII) oxide (\( Mn_2O_7 \)) is significant because it is a highly reactive and unstable compound that can lead to an explosion when it decomposes or reacts further.

### Conclusion
Thus, the explosion occurs due to the formation of \( Mn_2O_7 \) when concentrated \( H_2SO_4 \) is added to \( KMnO_4 \).

### Final Answer
The correct answer is \( Mn_2O_7 \).
