The acid rain does not contian

Options

A. Sulphuric acid
B. Nitric acid
C. Sulphurous acid
D. Acetic acid

Answer

**Step-by-Step Solution:**

1. **Understand the Concept of Acid Rain:**
Acid rain is formed when sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the atmosphere. These compounds react with water vapor and other chemicals in the air to form acids.

2. **Identify the Common Acids in Acid Rain:**
The primary acids associated with acid rain include:
- Sulfuric Acid (H2SO4)
- Nitric Acid (HNO3)
- Carbonic Acid (H2CO3)
- Sulfurous Acid (H2SO3)

3. **Analyze the Given Options:**
The question provides four options:
- A) Sulfuric Acid
- B) Nitric Acid
- C) Sulfurous Acid
- D) Acetic Acid

4. **Determine Which Acid is Not Present:**
- Sulfuric Acid (H2SO4) is formed from the reaction of sulfur dioxide with water and oxygen.
- Nitric Acid (HNO3) is formed from nitrogen oxides reacting with water.
- Sulfurous Acid (H2SO3) can also form from sulfur dioxide and water.
- Acetic Acid (CH3COOH), however, is not formed from these reactions and is not a component of acid rain.

5. **Conclude the Answer:**
Based on the analysis, the acid that is not contained in acid rain is **Acetic Acid (CH3COOH)**. Therefore, the answer is **D) Acetic Acid**.
