5.6
The average pH of pure unpolluted rain is around 5.6. This acidity is due to the dissolved carbon dioxide in the atmosphere forming carbonic acid.
The pH of unpolluted rainwater is typically around 5.6, which is slightly acidic. This acidity is primarily due to the presence of carbon dioxide in the atmosphere, which forms carbonic acid when dissolved in water.
If water is unpolluted, fish thrive in it.

The stream was unpolluted and clean. The ground was unpolluted with the toxin.
It depends where it is.
The rain water is very useful for growth of plants because it is mostly unpolluted and also leaching of salts takes place in the vecinity of plants.
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
The rain water is very sweet and unpolluted. The tap water is safe to drink but tastes and smells of chemicals. Some of the tap water comes from catchments, desalination plants and recycled (mainly used on public gardens).
Acid rain" is a popular term referring to the deposition of wet (rain, snow, sleet, fog and cloudwater, dew) and dry (acidifying particles and gases) acidic components. A more accurate term is "acid deposition". Distilled water, which contains no carbon dioxide, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are bases. "Clean" or unpolluted rain has a slightly acidic pH of about 5.2, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid (pH 5.6 in distilled water), but unpolluted rain also contains other chemicals.[1]
To keep water unpolluted, you can: Properly dispose of waste by recycling and using designated disposal sites. Avoid using harmful chemicals and pesticides that can runoff into water sources. Support and participate in clean-up efforts for rivers, lakes, and oceans.
