Fuming nitic acid is a mixture of.

Options

A. `H_(2)SO_(4) + HNO_(3)`
B. `HNO_(3) +SO_(2)`
C. `HNO_(3) + SO_(3)`
D. `HNO_(3) + NO_(2)`

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Fuming Nitric Acid**: Fuming nitric acid is a concentrated form of nitric acid (HNO3) that contains dissolved nitrogen dioxide (NO2).

2. **Components of Fuming Nitric Acid**: The primary components of fuming nitric acid are:
- Nitric acid (HNO3)
- Nitrogen dioxide (NO2)

3. **Properties of Fuming Nitric Acid**: Fuming nitric acid is characterized by its strong oxidizing properties and is typically a yellowish liquid due to the presence of nitrogen dioxide.

4. **Health Hazards**: It is important to note that inhaling fuming nitric acid, even in small amounts, can be harmful and potentially fatal due to the toxicity of nitrogen dioxide.

5. **Conclusion**: Therefore, fuming nitric acid is a mixture of nitrogen dioxide (NO2) and nitric acid (HNO3).

**Final Answer**: Fuming nitric acid is a mixture of NO2 and HNO3.
