Which of the following statements regarding hydrogen peroxide is`/`are incorrect ?

Options

A. It is a strong oxidising agent.
B. It is decomposed by `MnO_(2)`.
C. It behaves as a reducing agent.
D. It is more stable in basic solution.

Explanation

To determine which statements regarding hydrogen peroxide (H₂O₂) are incorrect, we will analyze each statement based on the properties and behavior of hydrogen peroxide.

### Step-by-Step Solution:

1. **Identify the Chemical Formula**:
- Hydrogen peroxide is represented by the formula H₂O₂.

2. **Assess Oxidizing and Reducing Properties**:
- Hydrogen peroxide can act as both an oxidizing agent and a reducing agent.
- **Oxidizing Agent**: It can oxidize substances, such as converting iodide ions (I⁻) to iodine (I₂).
- **Reducing Agent**: It can reduce substances, such as converting silver oxide (Ag₂O) to silver (Ag).

3. **Evaluate Stability in Different Mediums**:
- Hydrogen peroxide is known to be more stable in acidic solutions compared to basic solutions. Therefore, any statement claiming it is stable in basic solutions is incorrect.

4. **Decomposition Reaction**:
- Hydrogen peroxide decomposes into water (H₂O) and oxygen (O₂) in the presence of catalysts like manganese dioxide (MnO₂). This statement is correct.

5. **Summarize the Statements**:
- Let's summarize the statements that are given:
- A) Hydrogen peroxide is a strong oxidizing agent. (Correct)
- B) Hydrogen peroxide decomposes in the presence of metallic oxides like MnO₂. (Correct)
- C) Hydrogen peroxide behaves as a reducing agent. (Correct)
- D) Hydrogen peroxide is stable in basic solutions. (Incorrect)

6. **Conclusion**:
- The incorrect statement regarding hydrogen peroxide is that it is stable in basic solutions.

### Final Answer:
The incorrect statement regarding hydrogen peroxide is: **"Hydrogen peroxide is stable in basic solutions."**
