Rain is not 100% pure water. While it's primarily composed of water, it also contains dissolved gases and other substances from the atmosphere.
Here's why:
- Dissolved Gases: Rainwater absorbs gases like carbon dioxide from the air, forming carbonic acid. This makes rainwater slightly acidic.
- Other Impurities: Depending on the environment, rain can also contain dust particles, pollutants, and even trace amounts of minerals.
While rain is not 100% pure water, it's still a vital source of freshwater for our planet.
