Which characteristic property of `H_(2)SO_(4)` is responsible for its chemcial properties

Options

A. low boiling point
B. weak acidic nature
C. acting as reductant
D. affinity for water

Answer

To determine which characteristic property of sulfuric acid (H₂SO₄) is responsible for its chemical properties, let's analyze the options and the nature of H₂SO₄ step by step.

### Step 1: Identify the Properties of H₂SO₄
H₂SO₄ has several notable characteristics:
1. **Low Volatility**: H₂SO₄ is a low volatile liquid, meaning it does not evaporate easily.
2. **Strong Acid**: It is a strong acid, which means it dissociates completely in water to produce H⁺ ions.
3. **Oxidizing Agent**: H₂SO₄ can act as an oxidizing agent in various chemical reactions.
4. **Affinity for Water**: H₂SO₄ has a high affinity for water, meaning it can absorb water readily.

### Step 2: Analyze Each Property
- **Low Volatility**: While this property is significant, it does not directly influence the chemical reactivity of H₂SO₄.
- **Weak Acidic Nature**: This is incorrect as H₂SO₄ is a strong acid.
- **Acting as a Reductant**: H₂SO₄ does not act as a reductant; instead, it is known for its oxidizing properties.
- **Affinity for Water**: This property is crucial as it allows H₂SO₄ to participate in reactions that involve the removal or addition of water, making it a strong dehydrating agent.

### Step 3: Conclusion
The characteristic property of H₂SO₄ that is primarily responsible for its chemical properties is its **affinity for water**. This property allows it to engage in various chemical reactions effectively, including dehydration reactions.

### Final Answer
The characteristic property of H₂SO₄ responsible for its chemical properties is its **affinity for water**.
