Which of the following statement incorrect?

Options

A. Acid rain is caused due to present of acids in rain
B. Acid rain has no effect on aquatic life
C. Acid rain can be reduced by clean fuels
D. Acid rain corrodes water pipes

Answer

To determine which statement is incorrect regarding acid rain, we will analyze each statement provided in the video transcript.

### Step-by-Step Solution:

1. **Understanding Acid Rain**:
- Acid rain is defined as rain that has a lower pH than normal rain, typically due to the presence of acids such as sulfuric acid (H₂SO₄) and nitric acid (HNO₃) in the atmosphere.

2. **Analyzing the Statements**:
- **Statement 1**: "Acid rain is caused due to presence of acid in rain."
- This statement is somewhat vague but not entirely incorrect, as acid rain does contain acids.

- **Statement 2**: "Acid rain is caused due to presence of nitric and sulphuric acid."
- This statement is correct. Acid rain is primarily caused by the presence of these two acids, which are formed from the reaction of sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) with water in the atmosphere.

- **Statement 3**: "If pH is below 5 then it is difficult to hatch the eggs."
- This statement is also correct. A pH below 5 can indeed affect the hatching of eggs for many species, as it can be harmful to aquatic life.

- **Statement 4**: "Acid rain can be reduced by clean fuel."
- This statement is correct. Using clean fuels can reduce the emissions of sulfur dioxide and nitrogen oxides, which are the precursors to acid rain.

3. **Identifying the Incorrect Statement**:
- The first statement is the least specific and can be interpreted as misleading since it does not clarify that the acids are primarily sulfuric and nitric acids. However, it is not outright incorrect.
- The other statements are accurate and provide specific information about the causes and effects of acid rain.

### Conclusion:
- The statement that is most likely to be considered incorrect or misleading is the first one: "Acid rain is caused due to presence of acid in rain."
