Today also the rainwater is generally poluted.
The pH value of unpolluted rainwater is typically around 5.6, which is slightly acidic due to the presence of carbon dioxide in the atmosphere.
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
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.
Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6. The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). Carbon dioxide (CO2) is present in the greatest concentration and therefore contributes the most to the natural acidity of rainwater. Hope this helps! :)
It's because there is already natural CO2 in the rain water (from the atmosphere), and CO2 is an acidic gas. In today's world, there is no such thing as unpolluted water. We have successfully polluted the atmosphere and our earth. Our water is full of hydrocarbons, pharmaceuticals, and a plethora of other toxins/pollutants.
Unpolluted rainwater can be slightly acidic due to the presence of carbon dioxide in the atmosphere, which reacts with water to form carbonic acid. This natural acidity of rainwater is typically very mild and not harmful to the environment.
No, it is normal

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.
Its natural.

The stream was unpolluted and clean. The ground was unpolluted with the toxin.
Unpolluted seawater is a cloudy/clear colour, formed from the natural water found in it and salt, among other things
If water is unpolluted, fish thrive in it.
