The range of pH for acidic rain is:

Options

A. 7
B. Below 7
C. Above 7
D. 14

Answer

To determine the range of pH for acidic rain, we can follow these steps:

### Step 1: Understanding Acidic Rain
Acidic rain is formed when pollutants like nitrogen oxides and sulfur oxides are released into the atmosphere, typically from burning fossil fuels. These oxides react with water in the atmosphere to form acids, namely nitric acid (HNO3) and sulfuric acid (H2SO4).

### Step 2: pH Scale Overview
The pH scale ranges from 0 to 14:
- A pH of 7 is considered neutral (pure water).
- A pH less than 7 indicates acidity.
- A pH greater than 7 indicates alkalinity.

### Step 3: Identifying the pH of Acidic Rain
Since acidic rain is caused by the formation of acids, its pH will be less than 7. The typical pH range for acidic rain is between 4 and 6. This means that while it is acidic, it is not as acidic as strong acids (which can have a pH close to 0).

### Step 4: Conclusion
Therefore, the range of pH for acidic rain is generally between 4 and 6.

### Final Answer
The range of pH for acidic rain is 4 to 6.
