Does rain water have a natural pH of neutral basic or acidic?

Answer 1

There are two reasons for rain water being slightly acidic:

1. some (weakly) acid forming CO2 from air is dissolved in it
2. other air pollutants like SO2 and nitric oxides (cars, indusry, smog) are even stronger acid forming

Answer 2

It depends on where you live. In New York City, for example, the rainwater is acidic. In other regions of the country it is more basic.

Answer 3

That depends on the source of the water in the river, what type of rocks or peat or earth etc it has percolated through.

Answer 4

Depending on the level of pollutants, rainwater runs from acidic to neutral (with acidic on the polluted end).

Answer 5

Rain water is neutral.

Answer 6

yes!
