On heating Potassium permanganate the product is obtained is/are : -

Options

A. Manganese dioxide
B. Potassium manganite
C. Oxygen
D. All of these

Answer

To solve the question regarding the products obtained from heating potassium permanganate (KMnO4), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: The compound in question is potassium permanganate, which has the chemical formula KMnO4.

2. **Understand the Decomposition Reaction**: When potassium permanganate is heated, it undergoes a decomposition reaction. This means that it breaks down into simpler substances.

3. **Write the Balanced Equation**: The balanced chemical equation for the decomposition of potassium permanganate upon heating is:
\[ 2 KMnO_4 \rightarrow K_2MnO_4 + MnO_2 + O_2 \]
This indicates that two moles of potassium permanganate yield one mole of potassium manganate (K2MnO4), one mole of manganese dioxide (MnO2), and one mole of oxygen gas (O2).

4. **Identify the Products**: From the balanced equation, we can identify the products formed:
- Potassium manganate (K2MnO4)
- Manganese dioxide (MnO2)
- Oxygen gas (O2)

5. **Conclusion**: Therefore, the products obtained on heating potassium permanganate are potassium manganate, manganese dioxide, and oxygen gas.

6. **Select the Correct Option**: If the options provided include manganese dioxide, potassium manganate, and oxygen, the correct answer would be "all of these."

### Final Answer:
The products obtained on heating potassium permanganate are potassium manganate (K2MnO4), manganese dioxide (MnO2), and oxygen (O2). Thus, the correct answer is "all of these."
