Answer:
The pH in water that comes from acid rain can reach up to 4, due to its combination with chemicals suspended in the air.
Explanation:
For this problem the options are:
A. 0
B. 4
C.10
D. 14
Normal rainwater typically has a pH of between 5 and 6 (average 5.5), but usually decreases when combined with polluting gases from industries and the use of fossil fuels.
Carbon monoxide, nitrogen oxides and sulfur dioxide are the main causes of acid rain, as combined with atmospheric water steam produce acids that are then part of precipitation, whose water has a pH of 4.
In addition:
- <em>0 is an extremely acidic pH.
</em>
- <em>10 and 14 (options C and D) correspond to strong bases.
