normal rain- 5.6 acid rain- 3 to 4
Any rain with a pH level below 5.6 is considered to be acid rain. If the pH is anything else that is above 5.6, it would not be considered to be acid rain.
pH is the scale used by scientists to express the aidity of acid rain.
Pure water has a pH of 7.0, while acid rain has a pH or 5.0 or less. The difference in pH would be 2.0 or greater, depending on how acidic the acid rain is.
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.
Clean rain has a ph of 5.6, while the ph of acid rain is 4.2-4.4.

The acid in the stomach has a lower pH than that of 'acid rain'. Therefore much more acidic.
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.
the answer is pH 7
Pure water has a pH of 7.0, while acid rain has a pH or 5.0 or less. The difference in pH would be 2.0 or greater, depending on how acidic the acid rain is.
Acid rain has a pH of 5.0 or less. Rain reacts with carbon dioxide in the atmosphere and forms a mildly acidic carbonic acid before it becomes rain.
when the rain has a pH of 4 and below. PH standing for the potential of hydrogen- the amount of acid in any liquid.
Neutral. pH below 7 is "acid rain."
Polution or just a low pH level in the rain. (low pH means stronger acid)
