Incorrect statement for `H_(2)SO_(4)` is

Options

A. High volatile
B. Strong acidic character
C. Dehydrating agent
D. Oxidising agent

Explanation

To determine the incorrect statement about sulfuric acid (H₂SO₄), we will analyze each statement provided about it.

### Step-by-Step Solution:

1. **Understanding Volatility of H₂SO₄**:
- Sulfuric acid is known for its low volatility. This means it does not easily evaporate into the gas phase.
- The reason for its low volatility is due to the formation of hydrogen bonds between its molecules, which keeps them associated even at higher temperatures.

**Hint**: Recall that volatility is related to how easily a substance can vaporize. Strong intermolecular forces lead to low volatility.

2. **Acidity of H₂SO₄**:
- H₂SO₄ is classified as a strong acid. Its pH is around 1, indicating that it dissociates completely in water to release hydrogen ions (H⁺).
- This property confirms that it is indeed a strong mineral acid.

**Hint**: Strong acids are characterized by their ability to completely dissociate in solution, leading to a low pH.

3. **Dehydrating Agent Property**:
- H₂SO₄ acts as a dehydrating agent, which means it can remove water from other substances.
- For example, when ethanol is treated with concentrated H₂SO₄, it can remove water to form ethene.

**Hint**: Dehydrating agents are substances that can remove water from other compounds, often leading to the formation of double bonds.

4. **Oxidizing Agent Property**:
- H₂SO₄ can also act as an oxidizing agent. For instance, when it reacts with HBr, it oxidizes bromide ions (Br⁻) to bromine (Br₂) while itself being reduced to sulfur dioxide (SO₂).

**Hint**: Oxidizing agents facilitate the oxidation of other substances while being reduced themselves.

5. **Conclusion**:
- After analyzing all the statements, the only incorrect statement is that H₂SO₄ is "highly volatile." In fact, it is low volatile due to strong hydrogen bonding.

### Final Answer:
The incorrect statement for H₂SO₄ is that it is "highly volatile."
