To determine the pH of normal rainfall, we need to understand the concept of pH, which is a measure of how acidic or basic a solution is. The pH scale ranges from 0 to 14, where:

- A pH of 7 is considered neutral.
- A pH below 7 indicates acidity.
- A pH above 7 indicates basicity (also known as alkalinity).

Normal rainfall has a slightly acidic pH due to the presence of dissolved carbon dioxide from the atmosphere, which forms carbonic acid in water.

Given the options:
- 5.6
- 000
- 7
- 3.2
- 8.3

From these options, the correct pH value for normal rainfall is 5.6, which indicates that it is mildly acidic.

Thus, the pH of normal rainfall is 5.6.
