Normal rain is slightly acidic, with a pH around 5.6 due to the natural presence of carbon dioxide in the atmosphere. Acid rain, on the other hand, has a lower pH (below 5.6), caused by pollutants such as sulfur dioxide and nitrogen oxides reacting with water in the atmosphere.
The highest ever recording was 4.9 i think in EuropeAnswer:Normal rain has a pH of 5.5 to 4.5. Acid rain has pH of anything less than 4.5 and reaches its strongest (lowest pH) value at about a pH of 2.The highest pH for acid rain (the weakest acid rain) would be at the lower value of normal rain water.
Acid rain is different to regular rain as it contains compounds of nitric oxide and other gases that have combined with water vapour in rain clouds to become acid rain...at least, i think so : )
The average rain pH in Philadelphia is around 4.3-4.5, making it slightly acidic due to pollution and atmospheric emissions.
Acid rain, of course. Though, to be correct, and because the acid is disolved in solution, this shoud be called acidic rain.
the normal pH of rain water is about 5.6
It has the pH of 5.6
Clean rain has a ph of 5.6, while the ph of acid rain is 4.2-4.4.
Normal rain has a pH of around 5.6, while acid rain has a pH lower than 5.6 due to higher levels of sulfur dioxide and nitrogen oxides, leading to increased acidity.
Normal clean rain has a pH value of between 5 and 5.5, which is slightly acidic
Acid Rain generally has a pH of less than 5, where normal rain is about 5.6. The lower the pH value, the more acidic is the rain.
A "normal" rain is considered to have a pH of 5,7. But the pH of acid rains can be as low as 2. The pH of rain is very variable on the Earth and during the year.
the pH of normal rain is said to be between 5.5 an 5. the pH is not 7 because carbonic acid is contained withing rain droplets from the atmosphere. this is how the atmosphere rids itself of toxins. pH of rain can also become very low when large amount of acid are present (from pollutants) the pH at which fish die in ponds when affected by acid rain is 4.9.

Normal rain typically has a pH of around 5.6 due to the presence of dissolved carbon dioxide, which forms weak carbonic acid. In contrast, vinegar, which is primarily acetic acid, has a pH ranging from about 2 to 3, making it significantly more acidic than rain. This means that vinegar is much more acidic than normal rainwater, which is only slightly acidic.
This will depend entirely on the area in question and atmospheric composition but usually the pH is just under neutral (7) due to dissolved Carbon Dioxide in the rain making it slightly acidic.
