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.
4.7
Polution or just a low pH level in the rain. (low pH means stronger acid)
around 4.7 and 4.8
well the pH level of the water

The highest pH level of acids is upto 14.
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.
A pH of 4
pH PA rain: 4.08 compared to 5.6
The pH of rainwater is normally from 6 - 6.5. Acid rain is rain with a pH of 5 and below.
The highest pH level of acids is upto 14.
The average PH level is between 4.17 and 4.94
a base
9.5 is the highest recommended.
4.8
4.7
